The Importance of Permeability in Modified Atmosphere Packaging

Posted on 24 September 2020

Modified Atmosphere packaging works two ways: it keeps the quality of the product in, and pests and contamination out. To keep the outer and inner world of the packaged product separated, you need a strong and reliable barrier. Not just against physical damages, but also chemical ones, such as microbiological contamination, oxidation, rancidity, loss of moisture. That’s where the permeability of your barrier comes in.

What is permeability in modified atmosphere packaging?

Permeability is the rate at which gases can pass through a material. There’s a great variety of materials to pick from whom all have different properties. When choosing the right packaging material, aka the barrier, you need to bear in mind the particular product and the gas mixture that will be used.

Why is it important?

You could say that a Modified Atmosphere is only as effective as the quality of the barrier. The correct barrier and right gas mixture will make the shelf life of your product longer.

If the permeability is too low, this can affect the oxygen and CO2 levels within the packaging.

When keeping the product and atmosphere safe, the goal is to use the right materials, not simply so many of something that it works as a barrier. Over-packaging is wasteful and has a great impact on the environment and costs you make in your supply chain. Masterpack effectively cuts back on this waste, by making tailor-made liners that fit your bag, rather than having to cut excess product.
