The Anatomy of Great Plastic Wide Mouth Bottles:

10 Parts to Know

 

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. Best of all, plastic wide mouth bottles are available in various types and sizes.

Amber Polyethylene Terephthalate (PET) plastic wide mouth bottles are best suited for storing pills, veterinary, and pharmaceutical products. These wide mouth bottles allow you to see the contents inside and can be used with a variety of closures. Their sizes range from 75cc to 750cc.

Clear PET plastic wide mouth round bottles are available in a variety of sizes from 75cc to 960 ml. They are lightweight, resistant to impact, and offer easy access to the contents inside. These bottles are often used in the laboratories and for storing items such as nutritional supplements..

White HDPE plastic wide mouth bottles are opaque white in color, recyclable and perfect for bulk packaging. Their size ranges from 75cc to 750cc. These wide mouth bottles are normally used for label application and silkscreen decoration.

Plastic Wide Mouth Bottles – 10 Parts to Know

Let’s take a detailed look at the architecture of plastic wide mouth bottles.

#1 FINISH – This is the part of wide mouth bottles 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 OR 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 wide mouth bottles. 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 packaging.

#5 NECK – The neck area is found below the finish. This is the section where the narrow part of wide mouth bottles 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 PANEL -The label panel is the flat area below the shoulder and just before the bottom of wide mouth bottles. 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 wide mouth bottles. As the name suggests, it is found on the lower section of the 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.

Why HDPE & PET Plastic Bottles Are So Popular

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

Safety of HDPE vs PET

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 food grade plastic cannot be underestimated. HDPE plastic is currently considered a low-hazard plastic with a low risk of leaching. PET plastic is approved as safe for food and beverage contact by the FDA and other regulatory agencies throughout the world, and has been for more than 30 years.

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, shampoo bottles, peanut butter, milk jugs, cooking oils, and food storage. Thirty years of testing has proven this plastic to be safe for contact with food packaging, drinks, and pharmaceuticals. Because it is resistant to micro-organisms and will not react to foods or biodegrade, and is 100% recyclable, PET is one of the most popular plastics to use. In fact, PET plastic is the most recycled plastic in the U.S and worldwide. 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? HDPE vs PET

People often ask the fundamental differences between HDPE vs PET plastic bottles. PET plastic is clear and glass-like while HDPE plastic is more opaque and flexible. Both are safe and are great options for consumables. HDPE bottles provide good stress crack resistance and impact strength along with a uniform wall thickness for better labeling and appearance. PET plastic containers are manufactured using a two-stage injection blow molding process. Clear PET bottles provide a great alcohol, solvent and moisture barrier.

Why Use Plastic? HDPE vs PET

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 in the battle between HDPE vs PET, both plastics are safe and are commonly used. The white bottles give further protection by blocking light.
