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.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.COPYRIGHT: (C)2013,JPO&INPIT【課題】 高温加熱滅菌処理を行っても変形が起こらず、しかも柔軟性および透明性に優れた、血液、薬剤等を入れる医薬用耐熱容器を提供する。【解決手段】 密度の異なるエチレン・α-オレフィン共重合体である成分[A]40~80重量%及び[B] 0~40重量%、並びに高密度ポリエチレン[C]3~48重量%からなり、DSC(示差走査型熱量計)の吸熱曲線から求めた滅菌温度での残存結晶化度が15~38重量%である樹脂組成物からなる内外層と下記成分[A] 70~90重量%、[B] 10~30重量%および[C]3~30重量%からなり、DSC(示差走査型熱量計)の吸熱曲線から求めた滅菌温度での残存結晶化度が10~22重量%である樹脂組成物からなる中間層の少なくとも3層からなる多層医薬用容器。【選択図】 なし
