<p>PURPOSE:To provide a medical bag which is improved in softness and transparency, and eliminates problems caused by elution of a plasticizer, stabilizer or the like into contents such as Ringer's solution or glucose liquid while having a strength enough to withstand a high temperature sterilization treatment by using a retort or an autoclave. CONSTITUTION:An inner layer made of a polyolefin based resin, an intermediate layer made of an ethylene-butene-1 copolymer, a propylene-butene-1 copolymer or a mixed resin of either of the copolymers with a polyethylene or a polypropylene and an outer layer made of a polyolefin based resin or a polyester resin are arranged to produce a laminated sheet by coextrusion. The material thus obtained is formed to a bag so that the inner layer in the laminated sheet makes an inner circumferential surface layer.</p> |
