Background
In film processing, one raw material is extruded onto another film that has been formed or films of different types that have been formed are bonded to one another to form a multilayer film, a product known as a composite film. The material of the composite film is mostly plastic, but paper, metal foil (usually aluminum) or fabric, etc. may also be used. The basic requirement of the composite film is that the adhesive properties between the layers be good to ensure the overall mechanical properties of the package. In addition, the composite film is mostly used for food packaging, an adhesive is used in the processing of the composite film, and the selection of a solvent and an adhesion process of the adhesive meet the corresponding requirements of sanitary standards. The co-extruded film has most of the characteristics of the composite film, but has a difference that all layers of the co-extruded film are extruded and formed at the same time, so that other non-plastic materials such as aluminum foil, paper and the like are avoided. The product has relatively few combination forms of materials and a small application range, but the winter-closure layers are combined by hot melting without an adhesive, so the sanitary safety of the food packaging co-extrusion film is relatively reliable;
