PURPOSE:To provide a film excellent in oxygen barrier properties, bending pinhole, resistance, toughness, non-curling properties or the like and suitable for the soft packing of food, drugs or chemicals and to effectively use a raw material polymer. CONSTITUTION:A polyamide type laminated biaxially stretched film is constituted by laminating layers selected from a layer (a) composed of a mixture of an aromatic polyamide polymer and a polyolefinic polymer, a layer (b) composed of an aliphatic polyamide polymer and a layer (c) composed of a mixture consisting of a polyamide polymer and a polyolefinic polymer and has layered constitution of (c)/(a)/(c) or (c)/(b)/(a)/(b)/(c). |
