Abstract
PURPOSE:To improve barrier property, resistance to moisture, sanitary characteristics, transparency and surface glossiness, by a method wherein the laminate of a polypropylene resin inner layer, a polycarbonate resin outer layer, an ethylene-vinyl alcohol copolymer intermediate layer and a hot-melt adhesive agent resin layer, interposed between the intermediate layer and the inner and outer layers, is molded through co-extrusion. CONSTITUTION:Polypropylene resin is one of resins prominent in sanitary characteristics and is prominent in resistances to heat and hot-water, further, is seldom extracted by the content of a vessel, therefore, it is used as an inner layer. Polycarbonate resin is prominent in transparency and the molded form thereof is excellent in surface glossiness, further, is provided with low- temperature high-impact properties and a proper rigidity, therefore, the same resin is used as an outer layer. Ethylene-vinyl alcohol copolymer can not be bonded to polypropylene or polycarbonate, therefore, a hot-melt adhesive agent layer is interposed between these plastics in order to provide them with adhesive property upon co-extrusion. A bottle or a tube, having combined characteristics, may be molded by molding the multi-layer co-extruded laminate through blow molding while heating it.
