EVOH co-extrusion film represents the highest level of high-barrier packaging materials. It is a multi-layer composite film formed by the co-extrusion blow molding or co-extrusion casting process, in which EVOH resin is combined with other polymers (such as PE, PP, PA, etc.) and an adhesive layer.
Through the precise multi-layer co-extrusion technology, it integrates the protective capabilities of the "King of Barrier" EVOH with the strength, heat-sealing properties and moisture resistance of polyolefins, presenting a top-level high-barrier packaging solution.
Despite the limitations of cost and humidity sensitivity, its unparalleled oxygen barrier ability and high transparency enable it to consistently hold a dominant position in fields such as food and medicine with extremely high preservation requirements. It is a model in modern packaging engineering that maximizes functionality through material combination.
