Ethylene Vinyl-Alcohol Copolymers (EVOH)
Ethylene Vinyl-Alcohol Copolymers, commonly called Ethylene Vinyl-Alcohol (EVOH), are high-barrier polymers known for their resistance to oxygen transmission. Ethylene Vinyl-Alcohol (EVOH) is often used in multilayer packaging, fuel systems, and other applications where oxygen, aroma, or gas barrier performance helps protect product quality and extend shelf life.
