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 polypropy lene 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 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.本發明之目的在於提供一種易剝離密封性、透明性、機械強度、對滅菌處理之耐熱性等優越,可防止添加劑對於容器收容液之溶出的多層薄膜,與使用其之容器。本發明之多層薄膜係依序積層第1層1、第2層2、第3層3、第4層4及第5層5者,其中,以丙烯-乙烯無規共聚物及/或聚丙烯均聚物形成第1層1,以丙烯-乙烯無規共聚物與α-烯烴彈性體之混合物形成第2層2及第4層4,以聚環狀烯烴與聚乙烯之混合物形成第3層3,以依90:10~10:90之重量比例含有聚丙烯均聚物與丙烯-乙烯無規共聚物的混合物形成第5層5。又,本發明之容器係由上述多層薄膜以第1層1為外層、第5層5為內層之方式所形成。1‧‧‧第1層2‧‧‧第2層3‧‧‧第3層4‧‧‧第4層5‧‧‧第5層
