PURPOSE:To enable the repeated use of the uneven shape of an ethylene/vinyl alcohol copolymer resin film having an uneven surface by successively laminating an olefinic adhesive resin film and an olefinic thermoplastic elastomer resin film to the ethylene/vinyl alcohol copolymer resin film. CONSTITUTION:A molten ethylene/vinyl alcohol copolymer resin 5 is applied to a cooling roll 6 having an uneven surface. An adhesive olefinic resin 4 having a functional group graft-polymerized therewith and an olefinic thermoplastic elastomer resin 3 are laminated to the ethylene/vinyl alcohol copolymer resin 5 to be extruded to the cooling roll 6. By this method, a shaped film 8 excellent in emboss reproducibility and heat resistance can be obtained. |
