<p>PURPOSE:To obtain a laminated film, excellent in heat sealing property, curling, moisture barrier properties and gas barrier properties, high in physical strength and agreable to touch by a method wherein the laminated film is constituted of an uniaxial molecular orientation thermoplastic resin film layer, an ethylene copolymer resin film layer and a metallic thin film processing thermoplastic resin film layer, laminated between said layers. CONSTITUTION:A laminated film is constituted of an uniaxial molecular orientation thermoplastic resin film layer 1a, containing 0.3-30wt.% of white inorganic grain having an average grain size of 0.01-50mum, an ethylene copolymer resin film layer 5a, containing a substance having blocking preventing effect, an antioxidant and 10wt.% or more of ethylene copolymer resin and having a melting point lower than the same of the uniaxial molecular orientation thermoplastic resin film layer, and a metallic thin film processing thermoplastic resin film layer 4, laminated between both film layers.</p> |
