PROBLEM TO BE SOLVED: To provide a laminated film which can express excellent gas barrier properties and good adhesiveness without causing delamination not only in a normal state but also after performing retort treatment, when used as the laminated film having an inorganic thin film layer and gas barrier properties, and which is produced easily and is excellent also in cost effectiveness.SOLUTION: The laminated film has a coating layer on at least one surface of a plastic base material film. The coating layer is obtained from a resin composition for the coating layer, which composition contains such an urethane resin that 50 mol% or more of a polyisocyanate component is constituted by a (hydrogenated) meta xylylene diisocyanate component and another resin having an oxazoline group as constituent components. In a total-reflection infrared absorption spectrum of the coating layer, a ratio (P1/P2) of the peak intensity (P1) of a peak having absorption maximum in a region of 1655±10 cmto that (P2) of another peak having absorption maximum in another region of 1530±10 cmsatisfies the relationship shown by the inequality:1.2≤(P1/P2)≤4.5. The amount of the coating layer to be stuck is set within a range of 0.05-0.2 g/m.SELECTED DRAWING: None |
