摘要 PCT No. PCT/JP94/00143 Sec. 371 Date Oct. 4, 1994 Sec. 102(e) Date Oct. 4, 1994 PCT Filed Feb. 2, 1994 PCT Pub. No. WO94/17772 PCT Pub. Date Aug. 18, 1994.A medical multilayer film chiefly for use in forming medical containers having a plurality of chambers comprises an inner layer, an intermediate layer and an outer layer each made primarily of a polyolefin, the inner layer being formed of resin mixture of an ethylene-alpha-olefin copolymer having a density of 0.930 to 0.945 g/cm3 and a polypropylene, the intermediate layer including at least one resin mixture layer of resin mixture of an ethylene-alpha-lefin copolymer having a density of 0.920 to 0.945 g/cm3 and an ethylene-alpha-olefin elastomer having a density of 0.880 to 0.890 g/cm3 in a mixing ratio by weight of 1:5 to 2:1, the resin mixture layer having a thickness of at least 85% of the overall thickness of the intermediate layer, the outer layer being formed of an ethylene-alpha-olefin copolymer having a density of 0.930 to 0.945 g/cm3. The film having this structure is excellent in any of heat resistance, transparency, flexibility, impact resistance and easily peelable sealing properties.
