EVOH Co-Extrusion Film

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.

Main Performance Features of EVOH Co-Extrusion Film

Unparalleled oxygen barrier property

This is the core advantage of EVOH co-extruded film. Under dry conditions, its oxygen barrier performance is unparalleled by any other plastic material, effectively preventing the oxidation, discoloration, and off-flavor of the contents, and significantly extending the shelf life of food.

Excellent aroma retention

Due to its dense molecular structure, it can effectively prevent the escape of aroma components and also prevent external odors from invading.

High transparency and glossiness

It can be made into a very transparent film, perfectly showcasing the contents and enhancing the product's grade.

Environmental and hygienic

Non-toxic and odorless, it complies with food contact safety standards. At the same time, its multi-layer structure helps achieve lightweighting and reduces plastic usage.
