Provided is a film which can be industrially coated easily and exhibits excellent gas barrier performance without being subjected to a high-temperature heat treatment. The film exhibits good gas barrier performance immediately after the production, and maintains the excellent gas barrier performance while exhibiting excellent hot water resistance and printing resistance. More specifically, provided are: a gas barrier laminated film including a resin layer on an inorganic thin film formed on at least one surface of a support film, the resin layer being formed by applying: (1) an aqueous dispersion containing polyvinyl alcohol (a), an ethylene-unsaturated carboxylic acid copolymer (b), and inorganic particles (c); (2) an aqueous dispersion containing an ethylene-unsaturated carboxylic acid copolymer (b), inorganic particles (c), and/or a cross-linking agent (d); or (3) an aqueous dispersion containing polyvinyl alcohol (a), an ethylene-unsaturated carboxylic acid copolymer (b), inorganic particles (c), and a cross-linking agent (d), to the inorganic thin film surface; and a method of producing the gas barrier laminated film.
A gas barrier laminated film comprising a resin layer which is obtained by applying an aqueous dispersion containing polyvinyl alcohol (a), an ethylene-unsaturated carboxylic acid copolymer (b), and inorganic particles (c) to a surface of an inorganic thin film which is formed on at least one side of a support film.
A gas barrier laminated film comprising a resin layer which is obtained by applying an aqueous dispersion containing at least one member selected from an ethylene-unsaturated carboxylic acid copolymer (b), inorganic particles (c), and a cross-linking agent (d) to a surface of an inorganic thin film which is formed on at least one side of a support film.
A gas barrier laminated film comprising a resin layer which is obtained by applying an aqueous dispersion containing polyvinyl alcohol (a), an ethylene-unsaturated carboxylic acid copolymer (b), inorganic particles (c), and a cross-linking agent (d) to an inorganic thin film which is formed on at least one side of a support film.
