    摘要： 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.

    摘要： A biaxially stretched heat-shrinkable laminated film is disclosed which possesses good heat-shrinkability, excellent melt hole resistance and heat-resistant sealing property (the heat resistance of a seal portion), and highly satisfactory cold resistance, retains transparency even after shrinkage, and serves advantageously as a wrap for packaging foodstuffs. The laminated film is provided as an oxygen barrier layer with a layer of a mixture of vinylidene chloride resin and a low melting point polyamide resin having a crystalline melting point of not higher than 210.degree. C. This mixed resin has been cross-linked by applying the electron beam to the laminate in a dosage in the range of 1 to 12 megarads. The laminated film exhibits a heat shrinkage percentage of not less than 15% at 90.degree. C. and excels in gas barrier property.
