PROBLEM TO BE SOLVED: To provide a gas barrier film for holding high optical density/barrier properties and appearance beautifullness with respect to acidic content. SOLUTION: A copper vapor deposition layer of 5-20 ng/cm<SP>2</SP>is formed at least on one side of a plastic film base material and an aluminum vapor deposition layer is subsequently formed on the copper vapor deposition layer. Further, a coating layer with a thickness of 0.5-2.5μm formed by the reaction of a resin and a curing agent is formed on the aluminum vapor deposition layer. COPYRIGHT: (C)2005,JPO&NCIPI
