Medical multilayer film and use thereof

摘要

Disclosed are a medical multilayer film and use thereof. More specifically, disclosed are a medical multilayer film including: an outer layer comprising a propylene polymer selected from the group consisting of a polypropylene, a propylene copolymer and a combination thereof, an intermediate layer comprising 10 to 60% by weight of a propylene polymer selected from the group consisting of a polypropylene, a propylene copolymer and a combination thereof and 40 to 90% by weight of a thermoplastic elastomer, and an inner layer comprising 60 to 80% by weight of a propylene polymer selected from the group consisting of a polypropylene, a propylene copolymer and a combination thereof, 10 to 30% by weight of polyethylene, and 1 to 10% by weight of a thermoplastic elastomer, and use thereof. The multilayer film exhibits superior transparency, heat resistance and sealability as well as cold resistance, heat resistance, drop impact resistance and low-temperature impact resistance, thus being applicable to infusion solution containers, medical pouches, contrast medium containers and blood containers for packaging and administering medical solutions such as infusion solutions and blood.

1. A medical multilayer film for packaging and administering medical solutions comprising:
an outer layer comprising a propylene polymer selected from the group consisting of a polypropylene, a propylene copolymer, and a combination thereof; an intermediate layer comprising 10 to 60% by weight of a propylene polymer selected from the group consisting of a polypropylene, a propylene copolymer in which propylene is a main component of the copolymer, and a combination thereof, and 50 to 90% by weight of a styrene-based thermoplastic elastomer; and an inner layer consisting essentially of a blend of 60 to 80% by weight of a copolymer of propylene, ethylene and 1-butene, 10 to 30% by weight of a copolymer of ethylene and alpha-olefin, and 1 to 10% by weight of a styrene-based thermoplastic elastomer.
