Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a multilayer film excellent in heat resistance, strength, sealability, transparency, flexibility, gas/moisture permeability and the like, and also to provide a container which sufficiently suppresses occurrence of bulging at a long time preservation of a chemical or the like, an aging reduction of a liquid content, a bag breaking or the like. SOLUTION: The multiplayer film comprises five layers, the first layer which is made of an intermediate/high-density linear ethylene α-olefin copolymer or aliphatic polyamide resin, the second layer which is made of a mixture of a resin containing a linear ultra-low density ethylene α-olefin copolymer as a main component and a modified polyolefin unsaturated carboxylate, the third layer which is made of a cyclic olefin copolymer, the fourth layer which is made of a mixture of a resin containing a linear ultra-low density ethylene α-olefin copolymer manufactured by using a metallocene catalyst as a main component and a modified polyolefin unsaturated carboxylate or the like, and the fifth layer which is made of an intermediate/high density linear ethylene α-olefin copolymer. The container comprises the first layer of the multilayer film as an outer layer, and the fifth layer as an inner layer.
