PROBLEM TO BE SOLVED: To provide a multilayer container for medical treatment with an excellent steam barrier property, oxygen barrier property and with a low chemical adsorptive property.SOLUTION: A multilayer container for medical treatment includes a multilayer structure comprising the innermost layer and the outermost layer composed of a layer (A) having polyethylene naphthalate resin (A) as a main component and intermediate layers at least one layer of which is composed of a layer (B) having polyolefin resin (B) as a main component. The multilayer container, used for ampoules, vials and prefilled syringes, etc., has an excellent steam barrier property, oxygen barrier property, low adsorptive property, and its long-term storage property is greatly improved compared with conventional plastic containers for medical treatment.COPYRIGHT: (C)2013,JPO&INPIT【課題】水蒸気バリア性、酸素バリア性に優れ、薬液吸着性が低い医療用多層容器を提供する。【解決手段】最内層と最外層がポリエチレンナフタレート樹脂(A)を主成分とする層(A)からなり、中間層の少なくとも一層がポリオレフィン樹脂(B)を主成分とする層(B)からなる多層構造である医療用多層容器。アンプル、バイアル、プレフィルドシリンジ等が使用し、水蒸気バリア性、酸素バリア性に優れ、低吸着性であり、従来のプラスチック製医療用包装容器に比べ、長期保存性が格段に向上する。【選択図】なし
