PROBLEM TO BE SOLVED: To inexpensively provide a multilayered film for packaging having oxygen gas barrier properties, mechanical strength and sealability and excellent in surface printability. SOLUTION: The multilayered film for packaging is formed by laminating the outermost layer (A) with a wet tension of 36 dyn/cm or more, an oxygen gas barrier layer (B), a polyamide resin layer (C) and a seal layer (D) by a coextrusion method using an adhesive resin layer and the total thickness thereof is 60μm. The outermost layer resin is mainly manufactured from a copolyester resin, an ethylene/vinyl alcohol copolymer of which the ethylene copolymerization ratio is 38 - 47 mol% or copolymerized nylon with a melting point of 187 - 205°C. By this constitution, the surface printability of the outermost resin layer being a polyamide resin can be enhanced. COPYRIGHT: (C)2004,JPO
