PROBLEM TO BE SOLVED: To provide a laminate film, which can exhibit excellent gas barrier properties, does not undergo delamination and therefore can exhibit good adhesion properties, under ordinary conditions and moreover after being subjected to a retort treatment, when being made into a gas barrier laminated film provided with an inorganic thin film layer, and which can be easily produced and also has excellent cost effectiveness.SOLUTION: The laminate film is provided with a coated layer on at least one surface of a plastic base material film. The coated layer contains an oxazoline group and comprises an acrylic resin. The coated layer has a thickness (D) of 5 to 150 nm, and the ratio (P1/P2) of the peak intensity (P1) of a peak that has an absorption maximum in a region of 1655±10 cmto the peak intensity (P2) of a peak that has an absorption maximum in a region of 1580±10 cmin the total reflection infrared absorption spectra of the coated layer and the thickness (D) of the coated layer fulfill the relationship represented by the following formula: 0.03≤(P1/P2)/D≤0.15. |
