To provide a multilayer film and a container formed of the multilayer film which are excellent in unsealability, transparency, mechanical strength and sterilization heat resistance and are capable of preventing exudation of additives from the film into a liquid contained in the container. In a multilayer film including a first layer (1), a second layer (2), a third layer (3), a fourth layer (4) and a fifth layer (5) stacked in this order, the first layer (1) is composed of a propylene-ethylene random copolymer and/or a polypropylene homopolymer, and the second layer (2) and the fourth layer (4) are each composed of a mixture of a propylene-ethylene random copolymer and an ±-olefin elastomer. The third layer (3) is composed of a mixture of a polycycloolefin and a polyethylene, and the fifth layer (5) is composed of a mixture containing a polypropylene homopolymer and a propylene-ethylene random copolymer in a weight ratio of 90:10 to 10:90. A container is formed of the multilayer film with an outer layer and an inner layer thereof being defined by the first layer (1) and the fifth layer (5), respectively. |
