What is EVOH?

EVOH, officially known as Ethylene Vinyl Alcohol is a mixture of two polymers. It’s referred to as a copolymer. Specifically, it’s a mix of ethylene and vinyl alcohol.

For those with a technical mind, EVOH is prepared by the polymerization of ethylene and vinyl acetate. It creates a flexible form of thermoplastic which is commonly inserted between two layers of another plastic, such as PE.

Together, these layers can form a flexible yet dense layer of material which is difficult for most compounds to travel through.  

It’s worth noting that EVOH is crystal clear. However, when bonded with PE and other materials the bonding agent creates a tinted look.

In most cases, one layer of EVOH is sandwiched between two layers of another material, such as PE. However, it is possible to add additional layers when required.

What Does The PE Stand For?

PE is the abbreviation for Polyethylene. This is a type of plastic created by the polymerization of ethylene. The result is a resin which is light, versatile, and comparatively cheap to produce.

It is the most widely used type of plastic in the world, you’re certain to already own several things made of this plastic. For example, plastic bags, clear food wraps, shopping bags, detergent bottles, and even automobile fuel tanks.

It’s used in high-barrier bottles with EVOH to help create the strongest possible barrier at the most attractive possible price.

It’s worth noting that PE can be created in a variety of crystalline structures depending on how it is created. You may find it referred to as HDPE, LLDPE, and LDPE.

What Is A High Barrier Bottle?

High-barrier bottles are designed to keep scents and moisture out of whatever is inside the bottle. At the same time, these bottles are designed to be durable and can often be reused.

The key to choosing the right high-barrier bottle is to know what you want to protect the interior from. For example, PE plastic is very effective at preventing moisture from passing through it. However, it can’t stop gases from passing through it.

That’s why many high-barrier bottles use PE and EVOH, because EVOH is effective at stopping gases from passing through. However, EVOH does allow moisture through.

In short, a high-barrier bottle must be able to keep moisture, gases, and potentially other compounds out. You simply need to choose the right PE EVOH PE High Barrier Bottle for the job.

Why Are High Barrier Bottles Needed?

The majority of products created today are designed to last for weeks, months, or even years. Of course, maximising the shelf life of something that is perishable can be difficult. It needs to be stored where any possible contaminant can’t get to it.

That’s where high-barrier bottles step. The outer PE layer is excellent at keeping moisture out. This is important as moisture can seriously damage many stored products. For example, it can cause rust in metal containers, encourage bacteria to grow in foods, and even disintegrate paper packaging.

Equally, gases, such as oxygen, can help food spoil faster. It encourages the growth of bacteria and oxidises the food which will alter the taste and quality of the product. PE doesn’t prevent gases from passing through, but EVOH does.

Together, these two compounds create an effective barrier to moisture and gases, ensuring the contents of the bottle will last as long as possible.

As society relies on the longevity of products, high-barrier bottles are essential.

Is EVOH Safe To Be Used In Food Packaging And Bottles?

EVOH, like any other compound used with food and consumable liquids, has been fully assessed by food safety organizations across the globe. In every case, EVOH has been shown to be safe to use with food products.

The layer of EVOH protects the contents inside the bottle from oxidisation and other complications caused by the ingression of gas.

It’s tested, safe, and commonly used with dry and wet food items.

How Does EVOH Work?

EVOH is generally put between two layers of another material. In these high-barrier bottles, the other material is PE. The EVOPOH layer is bonded to the inner and outer layers, ensuring it remains in place and provides the greatest possible protection.

Together with the PE, it creates a barrier which is effective at keeping moisture and gases out of the container. Or, ensuring they stay in the container.

EVOH does more than just prevent gases from passing through it. The material is surprisingly flexible and yet still durable. That makes it the perfect accompaniment to PE, allowing the layered plastic to form bottles and a variety of other containers.

It’s worth noting that EVOH is a type of thermoplastic, meaning it offers excellent protection against temperature changes. In addition, it won’t lose its shape or properties even when high-temperature items are placed inside the bottle for storage.

Is EVOH Recyclable?

Unfortunately, EVOH is not generally considered recyclable. One of the biggest issues is that EVOH is generally sandwiched between two layers of other plastic. To effectively recycle the EVOH you would need to separate it from the other layers of plastic.

This is generally very difficult, time-consuming, and costly. In short, recycling products with EVOH in isn’t a viable option

In addition, this type of plastic biodegrades exceptionally slowly. It’s slow enough that’s it’s not considered biodegradable. However, it can be mixed with other compounds to speed up the process of biodegradation.

The good news is that technology is constantly advancing. While it’s not possible to recycle EVOH today, it could be in the future.

How Do I Dispose Of Used High Barrier Bottles?

Because it isn’t yet practical to recycle EVOH, used products are generally incinerated. The good news is that incineration doesn’t produce toxic fumes or any other type of by-products.

This means EVOH is relatively environmentally friendly.

Of course, any materials burned with the EVOH may release toxic fumes. As a business, you’ll need to dispose of EVOH products in the usual manner Any labels you produce for your high-barrier bottles will need to specify that the bottle isn’t recyclable. It simply needs to be discarded into a bin.

Can PE EVOH prevent Gases From Passing Through It?

While gases can easily pass through PE, they can’t pass through EVOH. This is generally the reason why EVOH is included in high-barrier bottles. The EVOH prevents oxygen from getting through; While oxygen is essential for life, its addition to food products causes oxidisation.

In effect, the oxygen causes any fats in the product to go “off”. They will produce a stale and unpleasant odor. Vitamins in the product will oxidize, meaning they can no longer offer the same health benefits. Oxygen can even cause food to change colour. In short, keeping oxygen out of the food is essential.

It’s not just oxygen that EVOH keeps out. It can prevent virtually any gas from getting into your bottled product. As several others can also produce issues with the quality of the food, EVOH is essential if you want your product to last as long as possible.

How Does EVOH React To Oil And Organic Solvents?

EVOH is very good at resisting oil and organic solvents. When it is sandwiched between two layers of plastic it can effectively protect the contents of your bottle from a huge array of contaminants, including oil and organic solvents.

Why Is An EVOH Barrier A Good Idea?

In the first instance, it prevents gases from getting to your product, damaging it.

The knock-on effect is that your product will stay fresh and taste great, even when stored for an extended period. This will help you establish a reputation for high-quality products. That reputation can quickly spread and your business will experience an increase in consumers.

Whether you’re supplying food, drink, cosmetics, pharmaceutical drugs, or any other perishable item, you’ll find an EVOH barrier is indispensable.

Don’t forget, by keeping out gas, your EVPOH barrier will also keep out odours which could damage the quality of your product and your reputation.

What’s The Main Benefit OF PE EVOH?

The main benefit of PE EVOH is that the two compounds work together to keep moisture and gases out of your product.

EVOH is also highly resistant to hydrocarbons, oils, and even organic solvents. Alongside this, it’s surprisingly flexible and is even crack-resistant.

In addition, EVOH doesn’t just work well with PE. It can accompany various other plastics, such as PP, and LLPD.

Its effectiveness and versatility are the biggest benefits associated with using PE EVOH PE high-barrier bottles.
