<P>PROBLEM TO BE SOLVED: To provide a heat-resistant medical container for containing blood and medicines, which can be prevented from deformation even after high-temperature heating sterilization treatment, and is excellent in flexibility and transparency. <P>SOLUTION: The multi-layer medical container comprises at least three layers such as inner and outer layers, and an intermediate layer. The inner and outer layers are made of a resin composition containing 40-80 wt.% of the component [A] and 0-40 wt.% of the component [B] as ethylene α-olefin copolymers having different densities and 3-48 wt.% of high-density polyethylene [C], and having a residual crystallization degree of 15-38 wt.% at a sterilization temperature obtained based on an endothermic curve of DSC (differential scanning calorimetry). The intermediate layer is made of a resin composition containing 70-90 wt.% of a component [A], 10-30 wt.% of a component [B], and a 3-30 wt.% of the component [C], and having a residual crystallization degree of 10-22 wt.% at a sterilization temperature obtained based on an endothermic curve of DSC. <P>COPYRIGHT: (C)2013,JPO&INPIT |
