Ethylene Vinyl Alcohol Copolymer(EVOH)
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
Our ethylene vinyl alcohol copolymer is a special thermoplastic polymer without any plastic additive. It can be used to produce high oxygen barrier films, sheets and other various food packaging materials. Because of its superior gas barrier function, its application has been widened in recent years. Due to water absorption will impact its barrier property, it is usually used with multi-layer co-extrusion production equipments.
