Water and oxygen barrier recyclable cartridge film
The seven-layer water- and oxygen-barrier recyclable cylindrical membrane solves the problem of decreased barrier performance of EVOH and HDPE composite membranes under high humidity. It achieves both moisture and oxygen permeability less than one, reasonable film thickness, good dart impact strength, and the cylindrical membrane is made of a single material, which facilitates recycling.
