PROBLEM TO BE SOLVED: To provide a blood bag for fresh frozen plasma preparation having an inner layer with a heat seal property, having a low-temperature shock resistance, and having high blocking resistance, when being sterilized at a high temperature without any content, high hygiene, heat resistance and the like.SOLUTION: The blood bag for fresh frozen plasma preparation is formed of a multi-layered film of at least two layers or more, including a seal layer, where the seal layer constitutes an inner wall surface, and the seal layer is composed of a propylene-based resin composition. An integrated elution amount of the propylene-based resin composition up to 80°C by a temperature rising elution fraction (TREF) method is 10-30 wt.%.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】内層がヒートシール性を有し、低温耐衝撃性、内容物を入れずに高温滅菌した際の耐ブロッキング性、衛生性、耐熱性等に優れた新鮮凍結血漿製剤用血液バッグを提供する。【解決手段】シール層を備えた少なくとも2層以上の多層フィルムにより形成され、該シール層が内壁面を構成しており、該シール層はポリプロピレン系樹脂組成物からなり、かつ該ポリプロピレン系樹脂組成物が昇温溶離分別法(TREF法)において、80℃までの積算溶出量が10~30重量%である新鮮凍結血漿製剤用血液バッグ。【選択図】なし
