ABT: active barrier technology

PET packaging is totally on trend. Although PET was mainly used to make drink bottles in the past, the material is now also being used in a range of other areas – including for salad packaging. One reason for this development is the material’s high degree of transparency, allowing consumers to take a look at the product inside the packaging while it is still on the store shelf. In addition, PET scores points for its valuable properties that
enhance sustainability – recycled PET is currently the only material with a positive EFSA opinion that can be used for food packaging purposes.

How does it work?

PET has strong barrier properties. However, some products require protection above and beyond this level – for instance, to prevent oxygen penetration. An active barrier can be used to meet these requirements and significantly prolong the food’s shelf life. This involves mixing an additive in with the PET granules. The oxygen is absorbed by the additive, rendering it “harmless.”
