Abstract: PROBLEM TO BE SOLVED: To prepare a gas barrier film having high gas barrier property even under high humidity and excellent in coating film adhesiveness, by specifying the atom number ratio N/C on the coating film layer side of a substrate film and by forming a coating film composed of specific components on the substrate. SOLUTION: This gas barrier film is obtained by providing a thermoplastic resin substrate film with a coating film consisting mainly of (A) a water-soluble polymer (pref. polyvinyl alcohol) and (B) an inorganic lamellar compound (e.g. kaolinite) and specifying the atom number ratio N/C on the surface of the coating film layer side at 0.001-0.1. The substrate film is pref. a polypropylene composite film prepared by laminating a base layer consisting mainly of a polypropylene polymer with a resin layer consisting of a blend of a polypropylene copolymer and an ethylene copolymer at the weight ratio of (95:5) to (75:25). In this case, it is recommended to provide the surface of the resin layer with a coating film layer. To set the N/C ratio within the above range, it is recommended that, prior to coating film formation on the surface of the coating film layer side of the substrate film, a corona discharge treatment, etc., be performed on the surface.
