PURPOSE: To produce a laminated polyamide film excellent in pinhole resistance, gas barrier properties, transparency and the uniformity of physical properties in the lateral direction of the film. CONSTITUTION: A substantially non-oriented sheet consisting of two or more layers formed from a layer (X) composed of nylon 6 or polyamide (A) based thereon, and a layer (Y) composed of a mixture consisting of 90-99wt.% of polyamide (B) consisting of a xylilenediamine component and a 4-12C aliphatic dicarboxylic acid component, and 10-1wt.% of aliphatic polyamide (C) is simultaneously stretched biaxially within a temp. range from 150 deg.C to (the m.p. of polyamide (A) -15 deg.C). In place of the resin layer (Y), a layer (Z) composed of a mixture of 90.00-99.95wt.% of polyamide (B) and 1.00-0.05wt.% of an inorg. nucleating agent is used. |
