Ethylene-Vinyl Alcohol Copolymer (EVOH)
Ethylene-Vinyl Alcohol Copolymer (EVOH) is a type of plastic made by combining ethylene and vinyl alcohol units. It is well-known for its excellent barrier properties, meaning it can effectively block gases, moisture, and odors. This makes EVOH ideal for packaging food and beverages to keep them fresh. Despite being flexible and transparent like common plastics, it provides superior protection against spoilage. EVOH is often used in multilayer packaging films, wine bottles, and medical packaging, balancing durability with barrier performance for preserving product quality.
