<p>PURPOSE:To obtain a film and a container superior in heat resistance, resistance to blocking, tensile strength, and the like and suitable for a medical use by a method wherein an outer layer is made of a biaxially oriented polyolefin resin, an intermediate layer is made of a flexible polyolefin resin, and an inner layer is made of a heat-resistant polyolefin resin. CONSTITUTION:An outer layer is made of a biaxially oriented ethylene.alpha-olefin copolymer having a density of 0.960g/cm<3> or more or a biaxially oriented polypropylene. A flexible polyolefin resin used for an intermediate layer is a straight-chain ethylene.alpha-olefin copolymer having a density of 0.920g/cm<3> or less. A heat-resistant polyolefin resin used for an inner layer is a straight- chain ethylene.alpha-olefin copolymer having a density of 0.925 to and including 0.950g/cm<3>.</p> |
