Abstract
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.
