  Ethylene-vinyl alcohol copolymer or EVOH is a flexible, crystal clear, and glossy thermoplastic copolymer with excellent flex-crack resistance, and very high resistance to hydrocarbons, oils and organic solvents. It also has some of the best barrier properties to gases such as oxygen, nitrogen, and carbon dioxide making it especially suited for   packaging  of food, drugs, cosmetics, and other perishable or delicate products to extend shelf life. In comparison with many other common films, EVOH has superior barrier properties. However, EVOH loses its good gas barrier properties when exposed to moisture. For this reason and to optimize both cost and performance, it is frequently used in multilayer, co-extruded films like HDPE, PP, and PET, which have superior moisture barrier properties. EVOH film for packaging has antistatic properties which ensures that dust particles in the atmosphere do not settle down on the packaging to prevent fungal growth that spoils the natural...
