PP EVOH PP High Barrier Bottle

EVOH stands for Ethylene-Vinyl Alcohol Copolymer. It’s a material which can flex without cracking and is effective at preventing substances such as oxygen, nitrogen, and carbon dioxide from passing through.

In other words, it’s a flexible, clear thermoplastic material which is perfect for containing food and drink.

That’s why you’re looking for PP EVOH PP high-barrier bottles and you’ll want to know the answers to the most frequently asked questions.

What Are PP EVOH PP High Barrier Bottles?

A PP EVOH PP high-barrier bottle is constructed with multiple layers. The middle layer is EVOH which is very effective at keeping air out of your bottle and locking the flavour inside.

Because it’s a strong material which doesn’t allow the flow of gases through it, a high-barrier bottle made with EVOH can help maintain the flavour of your product.

It works whether you’re selling flavoured water, spicy sauces, or anything in between.

The lack of gas flow also means the contents of your bottles will not be exposed to additional oxygen. As you know, oxygen entering your products causes oxidation.

Too much oxygen will damage the quality and taste of your product and can contribute to oxygen toxicity in your consumers. An EVOH high-barrier bottle prevents this from being an issue.

What Is EVOH Plastic?

EVOH, or Ethylene Vinyl Alcohol Copolymer is a type of plastic that is now commonly used in food packaging and drinks bottles. It’s usually positioned between the inner and outer plastic walls of bottles and other food containers. A thin layer of adhesive is used to join the EVOH to the inner and outer plastic walls.

EVOH is formed by merging two polymers together, specifically ethylene and vinyl alcohol. Because dual polymers are joined, EVOH is known as a copolymer.

Interestingly, the lower the ethylene content of EVOH the better it is at preventing gases from passing through. In contrast, higher concentrations of ethylene mean the plastic can be created at lower temperatures.

Why Is An EVOH Barrier Effective?

EVOH is best described as having an advanced molecular and crystalline structure. The density of this structure means that gases, particularly oxygen, carbon dioxide, and nitrogen, find it difficult to move through the EVOH.

While some oxygen and oxidisation can be beneficial to food and drinks, excessive oxygen will damage the flavour and quality of your product. Once you’ve created your product you usually don’t want additional oxygen getting to it.

The amount of oxygen which can pass through an EVOH barrier is close to zero, making it the perfect choice for any product which can be damaged by oxygen.

The density of the EVOH barrier is also an effective way to stop carbon dioxide, nitrogen, and other harmful gases from leaving your product. Carbon dioxide helps slow or eliminate bacterial growth and nitrogen pushes oxygen out.

Using an EVOH barrier means you can make sure your product has the right balance of gases and that it remains this while waiting to be sold.

What’s The Benefits Of Using PP EVOH PP High Barrier Bottles?

There are several benefits. Perhaps the most topical is that it’s an environmentally friendly solution. EVOH bottles can be made with recycled materials and the  bottles can be recycled afterwards.

That means less damage to the planet which is excellent for the planet and for your business reputation. Consumers will choose you just because you’re trying to look after the planet.

The resin used with EVOH enhances the look of the bottle, effectively making it sparkle. That will help your product appeal to c

In addition, because the food or drink is locked inside the bottle and protected from various gases, it will stay fresh for longer. That’s good for shelf life and customer appeal.

EVCOH packaging, including drink bottles, doesn’t contain the compounds which have been linked to endocrine illnesses.

Why Is EVOH A Better Option Than Traditional Plastic Bottles?

The most obvious reason is that EVOH bottles have a barrier which maintains the taste of the contents.

In fact, the EVOH can extend the shelf life of the product.

It does this by preventing oxidisation and reducing the amount of water which can enter the product compared to traditional plastic bottles.

As oxygen and moisture will damage the quality of the product and shorten its life, an EVOH bottle is the logical choice to keep your products fresh and maximise customer satisfaction.

If your product, whether food or drink, is perishable, you’ll benefit from using EVOH instead of traditional plastic.

EVOH offers more durability, better flex without cracking, is environmentally friendly, and will keep your product fresher for longer.

How Does EVOH Reduce Oxygen Permeation?

The basic principle is that molecular interactions in the EVOH prevent gases from moving through the plastic. The interactions adjust the molecular and crystalline structure which creates a dense material, gases, such as oxygen and nitrogen, are unable to move through the material.

In effect, they create a wall which oxygen and other gases can’t pass through.

Why Is Reduced Oxygen Permeation A Good Thing?

Oxygen is a necessary ingredient in many foods and drinks. The presence of oxygen causes oxidisation. The oxygen changes the molecules in the product, effectively ageing it faster.

This can be useful as part of the creation process as it enhances flavour. However, once the flavour is right, you don’t want to continue oxidising the product. It will adjust the flavour and shorten the lifespan of your product.

 Oxygen will also adjust the colour, texture, and even the consistency of any food or drink. Using an EVOH bottle means that the flavour and longevity of your product will be preserved, allowing customers to taste it the way you made it.

Are PP EVOH PP High Barrier Bottle Recyclable?

Yes! Until recently, EVOH has presented issues for recycling. This is mainly because it’s classified as a film and recycling machines struggle to deal with it.

However, it is now possible to recycle any material with EVOH in. Unfortunately, the process still needs work. Because EVOH is layered, and uses adhesive to stick to the layers, it is actually two types of plastic and they would need to be separated first.

It’s still possible. However, any plastic made from recycled EVOH is likely to have holes in it. That means the recycled plastic is significantly lower quality than the original.

While the exact uses of the recycled EVOH are still being defined, it doesn’t change the fact that this material can be recycled.

What Can PP EVOH PP High Barrier Bottles Be Used For?

It might be easier to ask what this type of bottle can’t be used for. The primary use of EVOH high-barrier bottles is in food production. However, it is also used in the medical industry and even in cosmetics.

Any perishable product can be stored inside an EVOH high-barrier bottle. The bottle will protect the product from an array of environmental factors, all of which can degrade the quality of the food, drink, medicine, or other products inside.

You’ll find these bottles are also commonly used to carry drugs. It’s not just about the lack of oxidisation and biological damage to the product. EVOH is flexible yet tough to crack, meaning it can help protect products, even when accidentally dropped.

Yes. EVOH has a special molecular makeup which gases and other compounds find hard to penetrate. This includes oxygen which can damage the cells in your product, adjusting the flavour and the life span of your product.

By helping to maintain the internal environment to exactly match the environment when you made it, you will prevent distortions in flavour and extend the lifespan of your product.

This only works with EVOH bottles. Those made from traditional plastic are prone to oxygen and other substances moving through them, effectively reducing the shelf life of any product;

You should note that EVOH bottles are also safer as the plastic is more rigid. This is a result of the layers and the molecular structure of EVOH. It means your product inside the bottle is better protected from accidents.

Why Should I Invest In PP EVOH PP High Barrier Bottles?

Quite simply, they are the future.

EVOH high-barrier bottles are stronger, less damaging to the environment, and are better at looking after your products.

What other reason do you need to switch to EVOH high-barrier bottles?

Is EVOH Resistance To Oil And Organic Solvents?

The EVOH layer, sandwiched between more traditional plastic and adhesive, is effectively impenetrable by oil and other organic compounds. That means an EVOH bottle can be left anywhere and the contents will remain intact.

Equally, you can put oily products inside the bottle and the oil won’t leach out. There is no risk of oily hand, reduced flavour, or even shortening the lifespan of your product.

How Does EVOH React To Sunlight?
