Abstract:
Ethylene–vinyl alcohol (EVOH) copolymers are excellent gas-barrier semicrystalline materials with very good chemical resistance and, as such, they are widely used in a number of packaging applications. One of the most widely implemented applications is that of an intermediate barrier layer in multilayer structures, to be used in various packaging designs for foodstuffs. The presence of EVOH in the packaging structure is key to food quality and safety because, for instance, it delays the ingress of oxygen, the agent responsible for a number of food deterioration processes. The effects of industrial processing ...
