Selecting the Right Bottle Color

The color of a bottle plays a major role in the presentation and protection of your products. It can be the source of much confusion too. Customers often start placing orders with us and we end up explaining why their products would make more sense in a different color.

We thought it would be helpful to offer a quick primer on the bottle colors offered by Silver Spur and where each of them shines.

Bottle Colors 101

Flint

Perfect for showcasing what’s in the bottle. Use Flint glass when UV rays aren’t a concern because it doesn’t offer light protection. Commonly used for food, beverages, liquor & more.


Amber

Ideal for products that require maximum UV protection or where minimal product visibility is desired. Amber bottles bring a pharmaceutical-grade feel to a product that radiates credibility.


Cobalt Blue

Offers significant protection from UV rays, although less than amber. Cobalt blue brings high product visibility and a natural/earthy feel to products. A favorite for many nutraceuticals.


Green

Provides a unique aesthetic for product differentiation. Green glass offers minimal UV protection, but more than flint. Often used for wine bottles and droppers.


There is a color, shape, and proper closure for all bottled products that can help your merchandise stand out from the crowd. Not sure which color makes the most sense for your product?  Feel free to contact us any time and we’ll be happy to help.

We know bottles like the back of our hand and actually enjoy talking about this stuff. Seriously!

Are Glass Bottles or Plastic Bottles Better?

colored variety of glass bottles and plastic bottles

There are plenty of options available when shopping for bottles but should you get glass or plastic bottles? It can be difficult to determine which type is better to buy. Continue reading to learn more about the benefits of each.

Benefits of Glass Bottles

One of the benefits of glass bottles is that they are 100% recyclable. They can be recycled numerous times without lowering the quality. In fact, 80% of glass containers get turned into new products. As a result, fewer emissions get produced and released into the air. The recycling process is fairly quick, with bottles going back onto shelves in about 30 days. These bottles are a preferred choice among people who are environmentally conscious.

Another reason to prefer glass bottles are that they protect the integrity of the contents inside them. Glass is useful for having an extremely low rate of chemical interactions. Food and beverages are less likely to lose their flavor. Silver Spur offers a wide range of glass bottles, including amber glass droppers. Amber glass often is used to protect oils, medicines, and other pharmaceutical products. Glass bottles that have a powder coating will prevent long-wavelength rays from damaging the products inside.

Overall, glass bottles tend to have higher durability. While they can break if dropped, they can last a lot longer. A person can use one of these bottles multiple times without the quality of the bottle decreasing. Glass bottles are less likely to get holes from daily use. Some types of glass bottles have additional strength. Thicker glass can improve a container’s durability. Powder-coated glass bottles have a higher resistance to chipping and scratching. The strength of glass bottles can help save money by not having to buy new bottles often.

Benefits of Plastic Bottles

One reason to choose plastic bottles is that they can easily be fashioned into different shapes, sizes and colors. One high-quality material is polyethylene terephthalate (PET). PET plastic gets used for shampoo bottles, salad dressings, and drink bottles. This type of plastic can be readily colored to signify its use. Handles and important markings can be added to the bottles. Plastic bottles will not only improve in their appearance, but they can become more efficient to use.

Plastic bottles can withstand extremely high and low temperatures. The type of material can impact the temperature range of the bottle. High-density polyethylene (HDPE) will have a much higher resistance to hot and cold conditions. HDPE plastic bottles can tolerate temperatures between –220 and 212 degrees Fahrenheit for a short period of time. They can be in conditions as low as –100 degrees Fahrenheit for a longer duration. PET plastic can also endure hot and freezing temperatures, but it has a smaller range than HDPE. If a food or drink needs to be stored in the freezer, then plastic bottles are the preferred choice.

Just like their glass counterparts, plastic bottles are recyclable. Different materials can be turned into other products like carpet fibers and strapping materials. One of the advantages of recycling plastic bottles is their low weight. As a result, the cost of transporting them to a recycling center is cheaper than with other types of bottles. Almost all plastic containers are recyclable, and each bottle gets categorized into different numbers. PET bottles are labeled as number 1 plastics, and HDPE is listed as number 2.

Glass and plastic bottles each come with their own merits. Silver Spur offers a wide selection of both types of bottles to meet your needs. To learn more, contact us today.

Top 5 Uses for Glass Packers

glass packers in cobalt and amber - Silver Spur Corp.

Have you ever wondered why most households prefer using glass packers as opposed to plastics or any other materials? Glass bottles have been available for ages. To date, glass packers are still a favorite among most households across the world.

Glass offers excellent strength, weight and compatibility for materials that cannot use plastic containers.  Glass packers are also preferred in many households since they are easier to clean. This is because they are unlikely to develop scratches that may harbor residue or bad odor.

Notably, glass bottles retain the taste of liquid placed on them without altering the original flavor. Glass is safer for use at home since it doesn’t have harmful chemicals that may pose a health threat to users. It is easier to identify whether glass is clean or not compared to other packing materials made of metal or plastics. Comparatively, glass packers can be reused for a more extended period of time without worrying about additional wear and tear.

Best of all, glass is 100% recyclable and can be recycled endlessly without loss in quality or purity. Most glass containers can go from a recycling bin to a store shelf in as little as 30 days. It’s estimated that almost 80% of recovered glass containers are made into new glass bottles.

This article stipulates a myriad of uses that glass packers can serve.

1. Administration of drugs

Are you running a clinic or have a small baby at home? A packer bottle style has a wide mouth for easy access, making it a good choice for packaging dry products such as tablets, capsules and powders.

The amber-colored glass shelters photosensitive compounds from light damage. This makes them the perfect choice for storing and dispensing medications, vitamins, flavorings and more.

2. Storage of laboratory chemicals

Typically, glass packers are the real deal in the storage of bases and acids. Ideally, ordinary glass is incapable of reacting chemically with various substances, including acids. In essence, glass cannot contaminate chemicals.

This is why glass packers are better at storing chemical substances in factories, laboratories, schools, and other entities that use chemicals for various reasons.

3. Used for preservation

Glass packers are also preferred in the preservation of food and beverages for a more extended period. Glass is not reactive to most substances hence ideal for use in the storage and long-term preservation of things such as syrup, pickles, jams, jellies, fruit and more.

4.  Used in sampling

Wide mouth bottles are used for sampling. Since it takes time to analyze soil samples, the glass packers are critical in the storage of sampled soil samples for future analysis.

5. Storage of food and beverages

Glass packers are effective in the storage of beverage and other food substances. Glass offers exceptional appeal when displayed on the shelves. In essence, It is easier to show off a product via glass bottles than plastics.

Additionally, products packaged in glass bottles never lose their taste. This means glass never affect product flavor or freshness in any way.

Health and safety standards

Glass bottles are the safest in storage since they are never affected by prevailing temperature changes. Unlike plastics that can melt and affect the quality of food substances, glass can maintain product quality on the shelf for the longest time possible.  In other words, packaging products in glass bottles ensure the products packed remain fresh without the worry of getting stale.

The use of glass packers in packaging is an essential element in ensuring high health standards are maintained. If you are looking for durable and quality bottles, contact us or request a sample to try out our glass packers. Let us help you find the right packaging solution today.

Ten Facts About Dropper Cap Assemblies To Sharpen Your Knowledge

dropper caps for wholesale glass dropper bottles

When you or your business is in need of wholesale glass dropper bottles, you probably don’t put much thought into the most important part of many products: the dropper cap assembly.

If you have ever used essential oils, CBD oil, or liquid medication, you’ll know that without the glass dropper, the liquid would not go to its intended place but would instead cause a mess. Valuable products would also be wasted due to the difficulty in pouring just the right amount from the bottle. Glass droppers help customers and those dispensing products to avoid the loss of valuable inventory.

What Are Dropper Cap Assemblies?

Dropper caps are made of three main parts: the rubber bulb, the plastic cap, and the glass pipette. Together, they form the cap of a glass bottle that’s meant to hold liquid. The rubber bulb is the “squeezable” part of the lid, the cap is simply the part that screws onto the bottle itself, and the pipette is simply the glass tube that is connected to the bottom of the cap and extends into the glass bottle. This assembly allows the user to safely remove liquid from the bottle and/or use just as much as is needed, one drop at a time.

The Physics of Dropper Caps

Dropper cap assemblies use the laws of physics to pull liquid from a glass bottle and into the glass tube. First, the user squeezes the rubber bulb on the lid. This forces out the air in the pipette and creates a vacuum. Then the pipette is inserted into the liquid and pressure is released from the cap. The vacuum needs to be filled, so the oil, medication, or other liquid has no choice but to go into the pipette.

The liquid then stays in the pipette until use. Anyone using a dropper cap assembly can then control the amount of product they squeeze out, thanks to the small hole at the end of the pipette. Once done, the extra liquid still in the pipette can simply be squeezed back into the bottle.

Types of Dropper Cap Assemblies

Regular dropper cap assemblies are simply that: a cap, a rubber bulb, and a pipette which may or may not be calibrated.

Another common type of dropper cap assembly is the “Euro” style. This style includes a dripper insert and is useful for bottles meant to hold fragrances, herbal extracts, and oils. It’s used for when precise measurements aren’t needed. The cap comes with the dripper already inside it and can be used by turning the bottle upside down and dripping a liquid one drop at a time.

Tamper-evident dropper caps have a ring that’s broken when the lid is unscrewed, and this allows you to easily see if a bottle has been opened before.

At last, CRC dropper caps are designed to be child-resistant.

Pipettes, and What They Do

The pipette is perhaps the most important part of a dropper cap assembly. They can be made of glass or even plastic, and they’re meant to draw liquid from a glass bottle and then dispense it. The great thing about pipettes is that they let you to dispense a liquid without spilling any extra drops or wasting any product.

To Contain, or To Dispense?

Pipettes are useful in a wide range of industries. Pipettes have two basic purposes. TC (To Contain) means a pipette is meant to hold a precise volume while TD (To Dispense) means that pipette has a design meant to squeeze out a very specific amount of liquid.  This is very useful for, say, dosing.

The Different Pipette Types

The regular type of pipette, or dropper cap, is simply meant to capture and dispense liquid. Etched pipettes have measurements on the pipette itself (typically in ml) and are meant for more specific jobs.

Uses Dropper Cap Assemblies

Dropper caps are useful for everything from pharmaceuticals to fragrances. CBD oil is dispensed using dropper caps and herbal remedies also make use of these products. Laboratories and schools can also find dropper caps with calibrated pipettes to be useful for their studies.

Different Styles and Colors

Since different colors of glass bottles exist, so do different colors and styles of dropper caps and pipettes. Amber pipettes can be ordered to match amber glass bottles, and caps with green pipettes can be ordered to match bottles of the same color. The most common type is flint, or clear, pipettes.

Dropper caps can also come in different colors (usually black or white) and as the regular Boston round cap or the Euro cap.

Different Bottles, Different Pipette Sizes

Pipettes also come in different sizes, ranging from 48mm to 100mm. You don’t want to have a pipette be so long that it touches the bottom of a glass jar, since glass is such a fragile material that easily breaks. It’s also a bad idea to have one be so short that it cannot reach the liquid on the bottom of a bottle.

Handy tables that are included on our product pages will help you find the right size.

Different Cap Materials

Plastics are most commonly used for dropper cap assemblies. Polypropylene and polyethylene are two common materials used to make up the caps, with Euro caps usually made of polypropylene. These materials don’t react with water, don’t easily crack and are durable, which help to prevent damage and leaks.

Offering Customers the Best

Dropper cap assemblies offer more options than it seems at first, and you can find the right type to suit your customers’ needs.

We offer dropper caps in several types that will meet your packaging and product needs. If you’re looking to keep your products safe and make them easy for your customers to use, contact us and we’ll help you find the right solution today.

Why HDPE & PET Plastic Bottles Are So Ideal

Thousands of plastic bottles pass through consumers’ hands each day, but rarely does anyone give a second thought to the container. It’s just something to hold a product in, until it fails. Maybe the lid doesn’t stay on or the bottle cracks. All of a sudden, there’s a problem and the reality hits. Quality storage containers make a difference. 

Safety

Bottles made from poor quality plastics are not durable or safe. Medicines improperly stored are a danger to children and pets. Faulty child-proof caps can allow children to access medications, causing overdoses. Each year, more than 34,000 children are sent to the emergency room after ingesting medication. Over 9,000 of them are hospitalized. 

Some plastics are unsafe and cause toxins to leach into the product. Foods and liquids stored improperly can absorb the toxins, especially when heated or stored over a long period of time. The importance of using the right plastic cannot be underestimated. 

PET Plastic Containers

Polyethylene terephthalate, more commonly known as PET or PETE plastic or polyester. This plastic is clear and strong but lightweight. It’s commonly used for drink bottles, salad dressings, shampoos, peanut butter, cooking oils, and food storage. Thirty years of testing has proven this plastic to be safe for contact with food, drinks, and pharmaceuticals. Because it is resistant to micro-organisms and will not react to foods or biodegrade, and is easily recyclable, PET is one of the most popular plastics to use. The FDA and other world-wide health organizations recognize PET’s safety. It does not contain bisphenol-A (BPA) or phthalate.

PET bottles can be easily decorated and molded into a wide variety of shapes and sizes. Their high clarity allows for good product visibility and they are easily colored to complement a brand and label. When you’re looking for protection of products such as pharmaceuticals or nutraceuticals, amber colored bottles offer high resistance to UV rays.

HDPE Plastic Containers

High-density polyethylene, or HDPE, is widely used in both rigid and flexible products. Its versatility allows it to be used for everything from hard hats to storage containers to bags. Lightweight yet strong and impact-resistant, this plastic has replaced many metals and wood for playground equipment, decks, and car parts, yet remains highly recyclable. It is FDA-approved and safe for food, liquids, and pharmaceuticals, and does not contain BPA or phthalate.

An important property of HDPE plastic is the ability to withstand cold temperatures. HDPE plastic can endure long-term temperatures of up to -100 degrees Fahrenheit. This allows products such as food and beverages to be frozen for later use. It also has the ability to withstand temperatures between 212 and -220 degrees Fahrenheit for short periods of time, making it sometimes suitable for autoclave sterilization.

What’s The Difference? 

PET plastic is clear and glass-like while HDPE plastic is more opaque and flexible. Both are safe and are great options for consumables. 

Why Use Plastic? 

Plastic is durable and lightweight, making it ideal for storage and more economical for transporting. Drug interactions and leaching can be an issue with certain medications and supplements, but both PET and HDPE plastics are safe and are commonly used. The white bottles give further protection by blocking light. 

Silver Spur Bottles & Closures

Silver Spur was founded in California in 1978 and quickly became well-known for their glass amber bottles. The business grew and now carries a large variety of glass and plastic bottles. Along with the amber, they also offer cobalt blue, flint, green, clear, and bottles.

The History of Boston Round Bottles

Amber Boston Rounds

Everybody talks about the discovery of fire and the invention of the wheel as humankind’s greatest achievements. But there’s another achievement that has an ancient history and a transformative effect on our way of life. 

The humble glass bottle. 

Bottles are so commonplace now that it’s hard to imagine them not existing. Our dive into the history of Boston Round bottles needs to begin with how bottles came about in the first place. 

When you start to think about everyday items in your home and workplace, you’ll find that you might know little about their histories. Objects we take for granted haven’t been around forever. Yet each one makes our lives easier. 

If you’re intrigued about the history of glass bottles and the Boston Round bottles, keep reading to see what we’ve uncovered. 

A Leap into the History of Glass Bottles

Before glass bottles, our ancestors made water containers from animal hides and gourds.

The first known invention of glass bottles was in ancient Egypt over 3000 years ago. The Egyptians made rudimentary glass bottles at first. They created a paste made from the natural substance silica and coated it in molten glass. 

Glass itself was invented two thousand years previous. It wasn’t until glass blowing techniques came about in 1st BC that the material was used for many applications. 

As glass bottles are durable and useful, they were made in increasing quantities as the centuries passed. Glass bottles were made on a mass scale with the invention of automatic glass blowing technology in the late 19th century. 

When Was the Boston Round Bottle Invented?

Whether you recognize the name or not, you’ll recognize the bottle. The Boston Round bottle is commonplace, particularly in drug dispensaries and pharmaceutical companies. 

In fact, you might well have a few in your bathroom cabinet. 

When glass bottles became easier to make in the 19th and 20th centuries, production shot up. They were particularly popular in the medicinal industry as glass is airtight and keeps odors out (or in). The ability to create dark-colored glass was also beneficial as it prevents UV from degrading light-sensitive medicines inside. 

Boston Round bottles could potentially have been designed to store liquids over solids as they have a narrow neck. This narrow diameter would’ve helped prevent any evaporation around the original cork stopper, something a solid, like a tablet, wouldn’t suffer from. 

There are no records to describe when the Boston Round bottle came about. This is possibly because many glass bottle suppliers existed in the late 1800s and 1900s, each offering similar bottles. 

Where Did Boston Round Bottles Get Their Name?

When glass bottle manufacturing took off in the pharmaceutical industry, bottles were commonly described by their shape. Bottles containing beverages, particularly carbonated drinks, were often round. This is because a round bottle has much more inherent strength than one of any other shape. 

The likelihood is that Boston Round bottles have “round” in the name purely as a shape descriptor. 

So why are they named “Boston”? 

Strangely enough, they were also referred to as Winchester bottles, particularly in the UK. Named Winchester Quart bottles, they were commonplace in 1860 at least when the Pharmaceutical Journal Part Two was published. The journal states, “…a Winchester quart bottle, which every druggist has in his store-room…”

It was named Winchester, not for the English city but after a measure at the time called a “Winchester”. 

There’s no indication of why Winchester Quart bottles are also known as Boston Round bottles, but they were a common bottle at the turn of the 20th century and manufactured by many glassmakers. 

What Are Boston Round Bottles Made From?

Traditional Boston Round bottles were made of glass, often brown-colored glass. This was most likely to protect its content from light. 

The bottle type has never gone out of fashion though thanks to its useful shape and these days it can be made out of glass or plastic. Glass is durable, easy to sterilize and 100% recyclable, making it an ideal material for storing a range of medicinal compounds. 

Plastic has the benefit of being lightweight and still strong. The Boston Round also features a threaded neck for a screw cap. These became common from 1930 onwards and took over from corks and glass stoppers as the most useful sealing method. 

Why Are They So Popular?

Whether you call them Boston Rounds or Winchester Quarts, the bottle shape has seen enduring popularity for over a hundred years. 

The rounded shoulder is useful for solids and creams as angled shoulders can cause the contents to get stuck. The narrow neck is traditionally beneficial for liquids, preventing evaporation and making it easier to pour accurately. 

As they’re round, they’re also exceptionally strong and more comfortable to handle. You can use them with many different types of tops as well. From pump-action tops to droppers and spray tops, manufacturers and buyers like the variety of usage. 

These days, you can buy Boston Round bottles in a wide variety of colors. From clear and brown to blue and green, both colored plastic and glass bottles are available to suit your needs. 

Boston Round Bottles Are Popular As Ever

The history of pharmaceutical equipment is fascinating and often overlooked. Boston Round bottles are such a popular shape that we all have instances of them around our homes. 

Useful for everything from oils and medicines to marijuana and creams, we can’t see the Boston Round falling out of favor. 

If you’re looking for Boston Round bottles, check out our selection. When you start using your new Boston Round bottles, you know you’ll be using a little piece of history.

5 Things To Consider When Buying Wholesale Glass Dropper Bottles

blue glass dropper bottles from Silver Spur Corp.

Glass dropper bottles represent an incredible value. Glass containers come with a surprising variety of customization options, are easily transportable in bulk, and can be very cost-efficient. Let’s dive deeper though; here are 5 things to consider when purchasing glass dropper bottles, and 5 compelling reasons to use glass droppers.

They come in a wide range of sizes

Glass dropper bottles can be tiny, or they can be relatively large. Silver Spur’s glass dropper bottles come in sizes that range from 5ml all the way up to 100 ml, with numerous, incremental sizes in between. Whether you are looking to bottle a small, medicinal product or essential oil to be applied on a drop-by-drop basis, or a larger-quantity medication, there is a bottle size made to fit your needs.

They are a safe storage method

Glass dropper bottles allow you to store all kinds of mixtures, medicines, and chemicals. Glass dropper bottles are primarily used to store and transport items like eye drops, liquid medications, CBD products, essential oils, ear care medications, hair care products, and other hygiene products such as soap or shampoo. Clever up-cyclers all over the world have also found ways to repurpose these versatile, safe bottles to hold just about anything. What makes them so useful though?

Due to the manufacturing processes used to make glass, dropper bottles are inert. That means that the few added materials used in their manufacture will not seep into the bottle’s contents and contaminate them. They are incredibly easy to transport and store, and are a naturally reusable resource that can either be repurposed or recycled regardless of what they contained inside.

They come in a variety of colors

The color of your glass dropper bottle matters. Although color can be used to make a product more attractive, lending increased branding utility to your droppers, color isn’t just for show. Colored bottles, especially amber bottles, help prevent chemical changes from occurring with the bottle by blocking harmful UV light from interacting with the liquid inside.

Silver Spur offers a range of colored bottle options including flint, green, blue, and amber that are ideal for both marketing purposes and to protect the integrity of the contents within.

You have a choice between dropper inserts

Dropper inserts are attachments that are used for administering the contents of the bottle in single-drop increments. Typically, dropper inserts are used with eye drops, ear drops, or hair care products.

There are two types of dropper inserts available: vertical or horizontal. Both give users exceptional control when dispensing the bottle’s contents, with the horizontal dropper insert giving the user a slight advantage, especially when self-administering solutions like eye drops.

There are a wide range of bottle closures available

If you don’t require a dropper insert, there are numerous types of bottle closures available to prevent the contents of the bottle from spilling during transport. They come in two different classifications: dispensing vs non-dispensing.

Dispensing closures feature a pipette that extends down into the bottle. One common type of dispensing closure is the bulb syringe that’s commonly paired with a dropper bottle. Non-dispensing closures do not have a pipette, but otherwise can be very similar. Both types usually come with a child-proof or tamper-resistant mechanism.

The advantage of wholesale

Glass dropper bottles are versatile and convenient. They come with a surprising amount of customization options, and can be employed for a near-infinite number of purposes. The biggest advantage to using glass dropper bottles is that their value increases as you buy them wholesale, without the typical worry of environmental impact. Silver Spur Corporation is your authority on glass dropper bottles. Please check out our product pages for our full line of bottles and packaging products.

The Anatomy of Great Plastic Wide Mouth Bottles

variety of plastic wide mouth bottles

Plastic Wide Mouth Bottles

Bottles come in all forms and sizes. That is why it’s vital to understand their anatomy to enable you to choose the most suitable one for your packaging needs. The mouth of a bottle can be sealed using an exterior bottle cap, an inner seal, internal stopper or closure. The type of product you deal with determines the kind of bottle you should use. Plastic bottles are best suited for keeping liquids like medicine, vitamins, oils, soft drinks, and water. They are popular because they are great moisture barriers and highly resistant to breakage from impact, whether during production or transportation. Also, they are affordable.

Plastic wide mouth bottles are available in various types and sizes. Amber Polyethylene Terephthalate (PET) plastic wide mouth round packer is best suited for storing pills, vet, and pharmaceutical products. This bottle allows you to see the contents inside and can be used with a variety of closures. The sizes range from 75cc to 750cc. The clear PET plastic wide mouth round bottle is available in a variety of sizes from 75cc to 960 ml. It is lightweight, resistant to impact, and offers easy access to the contents inside. These bottles are used in the laboratory. The white HDPE plastic wide mouth round bottle is opaque white in color, recyclable and perfect for bulk packaging. Its size ranges from 75cc to 750cc. The bottles are normally used for label application and silkscreen decoration.

Let’s look at the architecture of plastic wide-mouth bottles.

Plastic Wide-Mouth Bottles – 10 Parts to Know

1. Finish

This is the part above the neck, reaching up to the opening of a bottle. The finish is usually shaped in line with the type of closure used on the bottle. According to history, creating this part was the last step that craftsmen took when making containers, and hence the name.

2. Sealing surface/land

The sealing surface or land is the flat circular part of the finish that comes in direct contact with any closure used to seal the bottle. The land is usually flat to prevent contents from leaking from the container.

 3. Thread

This is the section of the finish that has a spiral shape. It is where the closure is twisted to seal the container. The size of the bottle neck determines the thread – standards range from between 5 threads per inch to 12 threads per inch. A well engineered thread will protect the bottle contents by keeping them fresh and free from being tampered with which can lead to product damage.

4. Transfer bead

Also known as the neck ring, this is the horizontal ridge found at the bottom of the finish section. This collar of plastic is used during the molding process and can be used to provide tamper evidence for your package.

5. Neck

The neck area is found below the finish. This is the section where the narrow part of the bottle gets smaller and joins the finish.

6. Shoulder

This section is where the base of the neck joins with the body. It is the widest part of the container. The shoulder’s slope can tell you how fast a product can spill out when you turn the container upside down.

7. Label

The label is the flat area below the shoulder and just before the bottom of a bottle. This is the section where labels or print decorations are placed.

8. Body

The body, also known as the sidewall, refers to the central part of the container. The body of most vessels usually is vertical. However, there can be exceptions.

9. Bottom

This is the foundation of a container. As the name suggests, it is found on the lower section of a bottle and falls right under the body. The bottom is divided into sections like the base, push-up, and heel. The heel refers to the section where the sidewall starts curving to form the base, which is the bottom part of the container. The push-up is part of the base and is the section that provides a plastic wide-mouth bottle with stability, and includes room for marking the base with details like registration numbers, and any labeling.

10. Parting line

This is a vertical line from the base to the finish. It’s where the two halves of the container meet during molding to form a full bottle.

Silver Spur Corporation can provide you with a variety of different types and sizes of plastic wide-mouth bottles in line with the product you want to package. Get in touch with us, and we’ll ensure you get the best plastic bottle for your packaging needs.

Why Amber Glass Droppers Are Perfect for Nutraceutical and Pharmaceutical Use

amber glass bottles

Most people don’t give this much thought, but amber glass is made a certain color and by certain materials for a reason.

If you think about all of the dark glass bottles you’ve encountered in your lifetime—beer bottles, cosmetic bottles and jars, essential oil bottles, and sublingual supplement bottles—you’ll realize that the majority of them have that amber color.

It’s safe to say that amber glass is in high demand across a multitude of industries. So, if your business is to supply manufacturers with the essential glass packaging for their products, then amber glass should be at the top of your supply list.

Amber Glass For Everyone

As mentioned above, amber bottles are made the way they are for a reason. The main reason being that if everything were put in clear bottles, our liquids, oils, and serums, etc. wouldn’t last very long. 

Many industries, including the pharmaceutical and nutraceutical industries, rely heavily on amber glass bottles but the list doesn’t end there. Other industries include:

It may seem like a short list, however, there are hundreds of thousands of different products out there that utilize amber glass.

Keep in mind that do-it-yourselfers are never in short supply either, and amber bottles are typically their first choice in product packaging.

How is Amber Glass Made?

Amber glass has some unique properties that make it a top choice for product packaging. While basic glassware and bottles are made from a liquefied form of sand that is heated and poured into certain shapes, amber glass is made a bit differently.

Amber glass is actually a mixture of sand, limestone, and soda ash. All of these elements are heated to a very high temperature.

When the mixture is completely melted and molten, other materials are added to the mix to give the glass its different properties and color depth. 

The elements of iron, sulfur, and carbon are usually added to the mixture to give the glass a nice dark coloring. The reason for this coloring is to protect the product inside, which we’ll talk about more later.

From there, machines and workers are used to shape the freshly made liquid glass into bottle, jar, or cup form. Once the glass cools, it begins to harden into its designated shape. 

How Amber Bottles Are Beneficial For Products

Glass, in general, comes with a variety of benefits for product manufacturers.

It’s considered to be inert, which means it won’t break down or seep chemicals into the products. It’s also relatively inexpensive since the materials that it’s made from are widely available.

And it can be tempered or have a variety of minerals and metals added to it for strength, and it doesn’t retain heat.

Amber glass, however, takes things to another level: 

It Protects Light-Sensitive Products

One of the main benefits of using amber glass is that it provides the best protection against UV light, blue light, and other light wavelengths under the 450-nanometer range. 

UV rays can cause what is known as photooxidation.

Photooxidation has the capacity to break down and alter the chemical makeup of a product, thereby cutting its shelf life in half or rendering it completely useless. In some cases, photooxidation can actually cause the ingredients within certain products to become toxic, causing adverse health reactions when used. 

The high level of protection from amber glass against different wavelengths of light allows for a longer shelf life of the product being stored. This is precisely what keeps beer fresh, essential oils potent, and allows cosmetics and skincare products to work with 100 percent efficiency. 

It Provides a Safer Interaction

Glass, in general, is made from natural materials, so manufacturers don’t have to worry about the bottles breaking down and leaking chemicals into the stored product.

This also means that there won’t be any chemical interactions between the glass and product inside, unlike plastic which is latent with chemicals that break down fairly easily and interact with the stored product.

It’s Versatile

Amber glass bottles come in a wide range of shapes, styles, and sizes.

They’re suitable for nearly every product, ranging from a 1 oz sample jar to an entire beer growler. Aside from skincare, cosmetics, and beer, amber glass is also suitable for storing chemicals and other raw materials—including acids and bases.

It’s Recyclable and Can Be Reused

Most glass is recyclable, but when there’s color involved, the rules can get a bit tricky. Amber glass is technically 100 percent recyclable—but it can only be broken down and reshaped into a new amber glass bottle, jar, etc. 

Amber bottles can also be cleaned and reused multiple times. Unlike plastic, they’re durable and take years and years to completely break down.

Not to mention, glass isn’t porous like plastic, so it’s perfectly safe to reuse.
