PROBLEM TO BE SOLVED: To provide a laminated film which can suppress gas permeability without impairing excellent characteristics, such as flexibility, elasticity, wear resistance, etc. of a thermoplastic polyurethane resin layer. SOLUTION: In this laminated film A, the thermoplastic polyurethane resin layer 1 is laminated and integrated with one surface or both surfaces of a thermoplastic resin layer 2 having lower gas permeability than that of the thermoplastic polyurethane resin layer 1. And, preferably the thermoplastic resin for constituting the thermoplastic resin layer 2 is an ethylene-vinyl alcohol copolymer or a polyamide series resin. COPYRIGHT: (C)2008,JPO&INPIT
