| 20090155550 | Pvdc-Polyolefin Coextruded Thermal-Formed High-Blocked Composite Packaging Material - A thermal-formed high-blocked composite packaging material of co-extruded PVDC-polyolefin is made up of the up film as the exploded view and the down film as the forming -film. The up film is BOPP/PE-TIE-PVDC-TIE-PP-PE which is co-extruded by the multi-layer flow or inflation film and formed by the dry of the solvent-free; the down film is the PP-TIE-PVDC-TIE-PE which is co-extruded by the multi-layer flow or inflation film. PVDC is homopolymerization of the polyvinylidene chloride or the copolymer of the methyl acrylate or the vinyl chloride, the PE is the polyethylene or the modified polyethylene, the PP is the polypropylene or themodified polypropylene. It can solve the problem of effective composite of the PVDC-polyolefin material in the condition of the co-extruding. The product has the high oxygen and water resistance, can be used for various packages of gasing, vacuumizing and thermal forming. | 06-18-2009 |
