GAS BARRIER MULTILAYER FILM

摘要

Disclosed is a film which can be industrially coated easily and exhibits excellent gas barrier property without being subjected to a high-temperature heat treatment. This film exhibits good gas barrier property right after production, and maintains the excellent gas barrier property while exhibiting excellent hot water resistance and printing resistance. Specifically disclosed is a gas barrier multilayer film having a resin layer on an inorganic thin film formed on at least one surface of a base film. The resin layer is formed by applying (1) an aqueous dispersion containing a 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 crosslinking agent (d); or (3) an aqueous dispersion containing a polyvinyl alcohol (a), an ethylene-unsaturated carboxylic acid copolymer (b), inorganic particles (c) and a crosslinking agent (d), onto the inorganic thin film surface. Also specifically disclosed is a method for producing such a gas barrier multilayer film.
