<p>PURPOSE:To provide a plastic container for medical liquid excellent in heat resistance and rigidity, and having a high transparency even if it is subjected to sterilization treatment at a high temp. CONSTITUTION:This container has a lamination structure of basic material layer 7, outer surface layer 8 and inner surface layer 9. The basic material layer 7 occupies at least 50% in thickness while the outer and inner layers 8, 9 at least 5%. The layer 7 is composed of a resin obtained by blending linear polyethylene in which the number of short chain branches of alpha-olefin is 1 to 20 while the density is 0.920 to 0.970g/cm<3>, with 10-50wt.% of polyethylene of low density by high pressure method. The layers 8, 9 are composed of propylene-ethylene copolymer in which the percentage content of propylene is 95-85mol.% while the percentage content of ethylene is 5-15mol%.</p> |
