The Benefits of Powder Coating Glass Bottles

The application of powder coats to glass bottles is an important element for many companies in the design, manufacturing, and retailing phases of their products. Powder coating offers several significant financial, environmental, and even visual advantages over other bottle treatment methods.

The following will discuss some of the key benefits of powder coating glass bottles, as well as common use cases across a wide range of industries.

How Modern Powder Coating Began

The first iteration of powder coating as we know it today originated in the 1940’s and 1950’s. Previously, the only way to apply organic polymers to a material’s surface was to spray coat them on, a process which was limited as to its efficiency and effectiveness.

However, in the early 1950’s a German scientist named Erwin Gemmer developed a method of applying thermostatic resins to a substrate by means of a fluid-bed application. Then in the 1960’s, the development of electrostatic application made it much easier to spray on even coats of powder across the surface of a workpiece. To this day, most manufacturers still use this simple and efficient electrostatic powder coating process to treat their products.

Benefits of Powder Coating Glass Bottles

What are some of the advantages that powder coating can offer to companies that deal in glass bottles? Here are just a few:

Enhanced protection against UV rays. Ultraviolet radiation can be harmful both to humans, and to many consumable products. While untreated glass typically blocks UV rays with short wavelengths (known as UVB), it does not offer much protection against long wavelength rays (UVA). However, the application of powder coating can block potentially damaging UVA radiation from reaching the product contained within the bottle.

Increased durability. Powder coated surfaces tend to be highly resistant to scratching, peeling, chipping, and other effects of normal wear and tear.

Improved eco-friendliness. Other spray-on processes that involve solvent-based wet paint often release volatile organic compounds (VOCs) into the atmosphere. These VOCs can damage the environment by contributing to ozone pollution and can also pose a health risk to humans exposed to them for a significant period of time. In contrast, powder coating releases very few, if any VOCs into the environment, making it the preferred choice for environmentally conscious businesses.

Wider branding capabilities. Since powder coating is such a versatile technique, companies that want to differentiate their products in a crowded market can utilize this process to create glass bottles that have a very distinctive look and feel. In addition, powder coated bottles can retain their color and texture for a long time, adding to a high quality experience for the end consumer.

Industries that Benefit from Powder Coating

There are several industries that frequently utilize powder coating methods to treat their glass bottles, including:

Food & Beverage

Exposure to UV radiation can, over time, change the taste and flavor of a premium wine, liquor and food. Wine-makers and other companies in the food and beverage industry often use powder coating to protect their products and give them a longer shelf life.

Cosmetics & Fragrances

Many companies in the health and beauty sector use powder coating techniques to protect body oils, colognes, and other items from UV damage. Powder coating can also make these products stand out from the crowd by customizing bottles with a unique style and design.

Nutraceuticals

From omega-3 fish oils to herbal remedies, many brands that specialize in natural supplements also use powder coating to treat their glass bottles, ensuring a long shelf life and increased product safety.

Without a doubt, powder coating is an integral manufacturing component for many businesses that package their goods in glass bottles. If you’d like to learn more about the benefits of powder coating, reach out to our friendly team of experts at the Silver Spur Corporation 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.

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.

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.

Why Amber Glass Euro Droppers Are Perfect for Nutraceutical and Pharmaceutical Use

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.

Keep reading to find out more about amber bottles and why you should always have them in stock.

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.   

Give Your Customers the Best

Amber glass is the best product packaging that you can have in stock for your customers.

It’s eye-catching, non-toxic, versatile, recyclable, affordable, and it offers the highest level of protection from light and chemicals. 

We offer amber glass bottles in all shapes and sizes that will fit all of your packaging needs. So, if you’re in the market for wholesale amber glass, contact us and our team will help you get set up right away.

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.
