PURPOSE:To provide an asymmetric multilayered stretched film having heat resistance, transparency, mechanical strength, barrier properties and heat sealability required as a laminating material for a packing film of food and the others or a solid industrial packing material and reduced in a curl phenomenon. CONSTITUTION:A multilayered stretched film is constituted of polyamide resin layer (A)/saponified ethylene/vinyl acetate copolymer resin layer (B)/polyamide resin layer (A')/adhesive resin layer (C)/seal layer (D) and characterized by that the sum of the thickness ratio of the polyamide resin layer (A) and that of the polyamide resin layer (A') is 50% or less and the thickness of the polyamide resin layer (A) does not exceed that of the polyamide resin layer (A'). |
