Multilayer film and container

Abstract

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 year (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 α-olefin clastomer. 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. The propylene-ethylene random copolymer contained in the second layer and the fourth layer is a mixture of a propylene-ethylene random copolymer (low-MFR propylene ethylene random copolymer) having a melt flow rate not less than 0.5 g / 10minutes and less than 5 g / 10 minutes as measured at 230°C and a propylene-ethylene random copolymer (high-MFR propylene-ethylene random copolymer) having a melt flow rate (g / 10 minutes) not less than 5 g / 10 minutes and not greater than 10 g / 10 minutes as measured at 230°C.
