[Problem] Disclosed is a subject that provides excellent oxygen barrier properties and adhesion between layers in the normal state and after wet heat treatment when a gas-barrier laminated film including an inorganic thin film layer is produced, and which is printed A laminated film that has good adhesion even during processing such as lamination, is easy to manufacture, and is also economical. [Solution] A laminated film characterized by having a cover layer on at least one side of a base film, the cover layer being formed of a resin composition for a cover layer containing a resin having an oxazoline group as a constituent, The cover layer has an inorganic thin film layer, and the inorganic thin film layer has a protective layer containing a polyurethane resin, the surface hardness of the laminated film is 350-700 N/mm 2 , and the arithmetic mean roughness of the protective layer in 2 μm square is Degree of 0.5 ~ 2.0nm. |
