<p>Disclosed is a plastic film for medical liquid containers, which includes at least three layers, each layer not containing a non-elastomeric block copolymer of propylene and a benzene-ring-free olefin except propylene such that the first layer which is composed mainly of propylene homopolymer, the second layer which contains polypropylene resin, polyethylene resin, and thermoplastic elastomer, and the third layer which funcitons as a sealing layer and is composed mainly of copolymer of propylene and another monomer, are laminated without the aid of bonding layer, with the second layer acting as an intermediate layer. The plastic film has desired properties of the medical liquid containers, such as low tendency to whiten by sterilization with high-pressure steam, low haze to permit inspection of its content after sterilization and being free from sticking, etc.</p> |
