a composite packaging material includes a top film and a bottom film as the forming film . the up film is bopp / pe - tie - pvdc - tie - pp - pe structure , which is co - extruded by multi - layer flow or inflation film and formed by a solventless dry way ; the bottom films has a pp - tie - pvdc - tie - pe structure which is co - extruded by multi - layer flow or inflation film . pvdc is homopolymerization of the polyvinylidene chloride or the copolymer of the methyl acrylate or the vinyl chloride , pe is polyethylene or modified polyethylene , and pp is polypropylene or modified polypropylene . the composite packaging material can solve the problem of effective composite of the pvdc - polyolefin material in the condition of the co - extruding , has high oxygen and water resistance , and can be used for various packages of gasing , vacuumizing and thermal forming .
