Abstract: An object of the present invention is to provide a plastic ampule capable of suppressing volatilization and scattering of a drug solution and elution of plastic compounding ingredients into the drug solution, as well as suppressing whisker formation and deformation and damage of an opening when the plastic ampule is opened. A plastic ampule 10 according to the present invention includes a drug solution storage part 11 for storing a drug solution, a drug solution discharge tube 12 in communication with the drug solution storage part 11 and extending toward one side, and a top part 13 closing an end at the one side of the drug solution discharge tube 12, and the drug solution discharge tube 12 includes a fragile part 14 formed to have a thin thickness along a circumferential direction.

Abstract: Disclosed is a multi-layer film comprising: a surface layer having a thickness of 10 to 50 ?Êm made of an ethylene-?-olefin copolymer having a density of 0.935 to 0.950 g/cm3, a flexible layer having a thickness of 100 to 200 ?Êm made of an ethylene-?-olefin copolymer having a density of 0.860 to 0.930 g/cm3, a barrier layer having a thickness of 10 to 80 ?Êm made of a mixed resin containing 60 to 95% by weight of a cyclic olefin polymer and 5 to 40% by weight of an ethylene-?-olefin copolymer having a density of 0.900 to 0.965 g/cm3, and a seal layer having a thickness of 5 to 80 ?Êm made of an ethylene-?-olefin copolymer having a density of 0.910 to 0.950 g/cm3. This multi-layer film is suited for use as a material for production of a medicine container 10 because it suppresses adsorption of a medicine by the barrier layer and is also superior in strength and flexibility.

Abstract: ABSTRACT Disclosed is a multi-layer film comprising: a surface layer having a thickness of 10 to 50 fÊm made of an ethylene-f-olefin copolymer having a density of 0.935 to 0.950 g/cm3, a flexible layer having a thickness of 100 to 200 fÊm made of an ethylene-f-olefin copolymer having a density of 0.860 to 0.930 g/cm3, a barrier layer having a thickness of 10 to 80 fÊm made of a mixed resin containing 60 to 95% by weight of a cyclic olefin polymer and 5 to 40% by weight of an ethylene-f-olefin copolymer having a density of 0.900 to 0.965 g/cm3, and a seal layer having a thickness of 5 to 80 fÊm made of an ethylene-f-olelin copolymer having a density of 0.910 to 0.950 g/cm3. This multi-layer film is suited for use as a material for production of a medicine container 10 because it suppresses adsorption or a medicine by the barrier layer and is also superior in strength and flexibility.
