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 processing.SOLUTION: A laminate film is provided with: a coating layer containing an acrylic resin and also containing a resin having an oxazoline group provided on at least one surface of a plastic base film; and an inorganic thin film layer provided on the coating layer. A variation ratio of surface roughness Ra of the laminate film before and after retort processing is 1 to 18%. |
