PROBLEM TO BE SOLVED: To provide a medical bag having high hygienic property and high heat resistance property which is excellent in flexibility, transparency, glassiness, and bag drop strength in a low temperature atmosphere.SOLUTION: There is provided a medical bag consisting of a laminate which is layered with at least a first layer, a second layer, and a third layer in this order. All of the first layer, the second layer, and the third layer contain the undermentioned component (A), and proportions of the component (A) contained in each resin layer satisfy the relationship of the first layer>the third layer>the second layer. Component (A): a copolymer of ethylene and a 3-12C α-olefin having the following characteristics (A-i) and (A-ii). (A-i): melt flow rate of 0.1-10 g/10 min (at 190°C and under 21.18 N load) (A-ii): density of 0.930-0.950 g/cm3.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】衛生性が高く、柔軟性、透明性、光沢に優れ、耐熱性が高く、低温雰囲気下での落袋強度が良好な、医療用袋の提供。【解決手段】 少なくとも第1層、第2層および第3層をこの順に積層した積層体からなる医療用袋であって、 第1層、第2層及び第3層の全てに下記成分(A)を含み、かつ、成分(A)の各樹脂層中に含有される割合が、第1層 > 第3層 > 第2層の関係を満たすことを特徴とする医療用袋。 成分(A):下記(A-i)及び(A-ii)の特性を有するエチレンと炭素数3~12のα-オレフィンとの共重合体 (A-i)メルトフローレート(190℃、21.18N荷重)が0.1~10g/10分 (A-ii)密度が0.930~0.950g/cm3【選択図】なし
