Barrier film is a type of plastic film that blocks gases like oxygen from passing through it easily. Materials like Polyamide (PA) and Ethylene Vinyl Alcohol (EVOH) are good at stopping gas, so they are called “barrier films.” The FROMM Barrier films Constructed from BOPA-PE (biaxially oriented polyamide and polyethylene), these multilayer films provide exceptional durability and barrier properties. FROMM offers high-performance barrier films designed for demanding packaging applications that require long-term air retention and mechanical strength. These films are compatible with various Airpad machines.
On the other hand, Polyethylene lets gas pass through more easily, so it’s not considered a barrier film. These films are often used to protect food or products that need to stay fresh longer.
