Abstract

Disclosed herein are a heat-resistant and oil-resistant laminate film comprising gas-barrier resin layer(s), thermoplastic resin layer(s) different from a gas-barrier resin and adhesive layer(s) disposed between the gas-barrier resin layer and the thermoplastic resin layer, produced by co-extruding a gas-barrier resin, a thermoplastic resin and an adhesive composition and irradiating the co-extruded laminate, the total number of the layers of the laminate film being not less than 3, and the adhesive layer comprising a cross-linked polymer and the adhesive composition consisting essentially of 100 parts by weight of a melt-extrudable adhesive resin and 0.1 to 50 parts by weight of a radiation-sensitive compound, and a process for producing the heat-resistant and oil-resistant laminate film.
