Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a laminated film for a medical container which can obtain the medial container high in transparency and excellent in heat resistance, flexibility, and bag making properties, the medical container using the film, and its production method. SOLUTION: The laminated film for the medical container is a tubular inflation laminated film formed by coextrusion. An outer layer is formed from polypropylene incorporated with 5-50 wt.% of polyethylene, and an inner layer is formed from polyethylene. The ratio (Mw/Mn) between the weight average molecular weight (Mw) and number (Mn) average molecular weight of the polypropylene forming the outer layer is 3.0 or below, and the ratio (Mw/Mn) between the weight average molecular weight and number average molecular weight of the polyethylene forming the outer layer is 3.5 or below.
