A multilayer film of the invention is a five-layer film composed of ethylene-.alpha.-olefin copolymer, wherein the density of a resin composing each layer is as follows, in order from the outer layer: First layer: 0.935 to 0.950 g/cm3 Second layer: 0.920 g/cm3 or less Third layer: 0.925 to 0.950 g/cm3 Fourth layer: 0.920 g/cm3 or less Fifth layer: 0.925 to 0.940 g/cm3 The container of the invention is formed by using this multilayer film, and is excellent in heat resistance, blocking resistance, tensile strength, flexibility, and transparency. The multilayer film and container of the invention are suited for medical applications, and others.

L'invention concerne une structure multi-couches consistant en 5 couches d'un copolymère d'.alpha.-oléfine d'éthylène. La densité des résines constituant ces couches est la suivante, en partant de l'extérieur: première couche: 0,935-0,95 g/cm?3¿; deuxième couche: 0,92 g/cm?3¿ au plus; troisième couche: 0,925-0,95 g/cm?3¿; quatrième couche: 0,92 g/cm?3¿ au plus; cinquième couche: 0,925-0,94 g/cm?3¿. L'invention concerne aussi un récipient, obtenu par montage de cette structure multi-couches, qui présente une résistance thermique, mécanique et à la traction, ainsi qu'une souplesse et une transparence élevées. Cette structure et ce récipient multi-couches conviennent donc bien pour des utilisations médicales.
