Abstract

The present invention relates to a multilayer medical film and to the use thereof, and more particularly, to a multilayer medical film comprising: an outer layer comprising one type of polypropylene polymer selected from the group consisting of polypropylene, a polypropylene copolymer, and the combination thereof; an intermediate layer comprising 50 to 70 wt % of one type of polypropylene polymer selected from the group consisting of polypropylene, a polypropylene copolymer, and the combination thereof, and 30 to 50 wt % of a thermoplastic elastomer; and an inner layer comprising 95 to 99.9 wt % of one type of polypropylene polymer selected from the group consisting of polypropylene, a polypropylene copolymer, and the combination thereof, and 0.1 to 5 wt % of polyethylene. The present invention also relates to the use of the film. The multilayer film has excellent transparency, heat resistance, and sealing properties, and prevents a blocking phenomenon in which the inner layers of films are adhered to each other during high temperature sterilization. Therefore, the multilayer film of the present invention can be used in sap receptacles for packaging and administering a medical liquid <u/> such as sap or blood, medical pouches, contrast media containers and blood containers.
