<P>PROBLEM TO BE SOLVED: To provide a laminate film having superior gas barrier properties and lamination strength, wherein a decrease in the gas barrier properties is small and interlayer delamination is less likely to occur even after retort treatment. <P>SOLUTION: A laminate film is provided, in which a coating layer, an inorganic thin film layer, and a protective layer are laminated on at least one surface of a base film. The coating layer is formed from a coating layer resin composition containing an acrylic resin and a resin having an oxazoline group, wherein a thickness (a) thereof and a predetermined two-peak ratio (P1/P2) in the total reflection infrared absorption spectra satisfy a specific relation. The protective layer is formed by applying coating liquid containing polyester resin having a weight average molecular weight of 22,000 to 40,000 and polyisocyanate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
