FILM FOR VAPOR DEPOSITION FILM AND GAS BARRIER FILM

摘要

PROBLEM TO BE SOLVED: To provide a film for vapor deposition that has a well-balanced combination of adhesion properties and gas barrier properties.

SOLUTION: The film for vapor deposition has an anchor coat layer formed from a urethane resin formed on at least one side of a film formed from a thermoplastic resin. In the film, the polyurethane resin is a polyurethane dispersion prepared by dispersing in water an aqueous polyurethane resin produced by reacting an isocyanate group-terminated urethane prepolymer with a chain extender and the isocyanate group-terminated urethane prepolymer includes an adhesive urethane prepolymer for imparting adhesion properties and a gas-barrier urethane prepolymer for imparting gas barrier properties.
