<P>PROBLEM TO BE SOLVED: To provide a laminated film having superior gas barrier properties and laminate strength in which deterioration in gas barrier properties is reduced and in which delamination hardly occurs even after retort processing. <P>SOLUTION: The laminated film includes, on at least one surface of a base material film, a coating layer, an inorganic thin film layer, and a gas barrier resin composition layer laminated thereon. The coating layer is formed of a coating layer resin composition containing resin having acrylic resin and oxazoline groups. In the coating layer, the film thickness (D) and the peak ratio (P1/P2) of prescribed two peaks in the total reflection infrared absorption spectra satisfy a specific relation. The gas barrier resin composition layer is formed of a gas barrier resin composition containing gas barrier resin constituted of an ethylene-vinyl alcohol copolymer, a specific amount of an inorganic layered compound, and a coupling agent and/or a crosslinking agent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
