Why Is High-barrier Packaging Better For Food?

If you want to retain the freshness of your food for longer, you need high-barrier film packaging. We all know it is one of the best materials for storing food, but why? In this article, we will answer the question, and you will learn a bit of science as you read.

How does high-barrier packaging work?

High barrier films are plastic sheets made with different layers of materials to give them robustness, strength, and impact the desired characteristics. They are made with a plastic base such as polyethylene or Polyethylene terephthalate, a vapor barrier such as silicon oxide film for food packaging, and a proprietary barrier coat layer.

What are the benefits of high-barrier packaging for food?

Preserves aroma and flavour

barrier films not only preserve the life of food but its quality. What makes food great is its taste, aroma, and flavour, which all contribute to a wholesome eating experience. The high-quality film provides a sealed barrier for your food items to prevent gases and malodor from leaking into and out of the food.


Prevents oxidative damage

Oxidative damage occurs when food is exposed to the atmosphere. Oxygen and other oxidants in the air cause different reactions in food and drinks that can cause them to discolour, go rancid, or rot. Ultra barriers prevent this due to their low oxygen transmission rate.


Protects against moisture damage

Similar to how barrier films protect food from oxygen and vapors, they prevent moisture from getting into food- this makes high-quality films great options for dry food items such as grains. Barrier films are also fantastic for food products such as meat and cheese by preventing vapors from getting inside.

Maintains inert atmosphere

An inert atmosphere such as nitrogen or carbon dioxide gas extends the shelf life of food products. The unique properties of superior flexible barrier thermoforming films make them suitable for maintaining an inert atmosphere for snacks and other products.

As you might have deduced, this is because of the ability to prevent the transmission of moisture and vapors in the packaging.

Minimal contamination

Not only does a high barrier film retain the composition of the content inside, but it also prevents external contamination and ingress. The effective film acts like a two-way barrier preserving the state of the food or beverage while shielding it from external sources like light, oxygen, moisture, and malodors that can corrupt the food.
