PROBLEM TO BE SOLVED: To provide a laminate sheet for forming a laminate tube body part showing excellence in a gas barrier property and transparency. SOLUTION: The laminate sheet for forming the laminate tube body part comprises a laminate of a heat-sealable film (I), a gas barrier film, a thin metallic film and a heat-sealable film (II) in this order from the innermost layer wherein the innermost heat-sealable film (I) and the gas barrier film, and the gas barrier film and the heat-sealable film (II) are bonded to each other by extruding a heat-welding resin, and the thin metallic film is 15 to 50μm. The laminate film causes little return of the tube and can prevent air absorption and oxidation of a content. COPYRIGHT: (C)2010,JPO&INPIT |
