What are the benefits of multilayer co-extruded blown film?

A very simple reason: the film directly between the performance of each other can complement each other, through the performance of each layer of the material between the complementary, high-performance composite film can be produced, so through the combination of PE, PA, TIE, EVOH, and other materials, through the multi-layer co-extrusion technology, can produce high-quality, high-performance film. Simply put, the advantages of a variety of materials are concentrated, costs can be effectively controlled, and the film structure can be adjusted according to the needs of a wide range of uses, until it becomes a variety of goods we see when we shop in the supermarket packaging.
