PROBLEM TO BE SOLVED: To prevent a metallic thin coat layer from becoming corroded by the hermetically packed content of a package formed using a laminated film for soft packaging and retain the gas barrier properties of the metallic thin coat layer contained in the laminated film for soft packaging by forming the thin coat layer which is corrosion-inhibitive to acids and salts, in the intermediate layer of the laminated film for soft packaging on which the metallic thin coat layer is laminated as a gas barrier layer. SOLUTION: A corrosion-inhibitive thin coat layer 4 of epoxy resin is interposed between the metallic thin coat layer 2 and the heat-sealable layer 3 of the laminated film for soft packaging formed by laminating a base material film layer 1, a gas barrier metallic thin coat layer 2 and the heat-sealable layer 3 in the order. Further, in the corrosion-inhibitive laminated film for soft packaging, the coat thickness of the corrosion-inhibitive thin coat layer 4 of epoxy resin is at least, 1μm or less.
