British made multifunctional new plastic food packaging

Recently, the British Huhta-maki company successfully developed a new type of plastic food packaging, which has both passive and active barrier functions, effectively inhibits oxygen infiltration, and even after food bag cooking, the effect will not be reduced.
The new packaging can not only extend the storage period of the product, but also can be directly heated by a microwave oven, which is particularly suitable for the packaging of convenient foods. According to reports, this new package, called "the sum of barriers," is composed of 6 layers of different materials. The first layer is polypropylene - a polymeric material with high oil resistance. The second and fourth layers are glue and glue, with oxygen-blocking polymeric material EVOH (passive barrier) in between. The fifth layer is an oxygen scavenger mixture called an active barrier that not only blocks the ingress of foreign oxygen molecules, but also absorbs oxygen in the package. The last is a layer of polypropylene material.
In the new package, the oxygen scavenger maintains its activity even in the presence of moisture, thus ensuring that the shelf life of the food remains unchanged.
