PURPOSE:To provide a polyamide resin compsn. and its stretched film excellent in oxygen gas barrier properties, resistance to pinhole formation due to flexing, toughness, etc., and suitable for the production of a packaging film for foods, drugs, chemicals, etc. CONSTITUTION:A mixture of a specific arom. polyamide and an aliph. polyamide is blended with a modified polyolefin in a specific amt. based on the arom. polyamide to prepare a polyamide resin compsn. The polyamide resin compsn. is melt-extruded into a substantially nonoriented and nonstretched sheet, which is then at least monoaxially stretched, followed by heat setting to obtain a stretched polyamide resin film. |
