A film for an infusion bag including: a surface layer composed of a polyamide resin composition, a heat seal layer composed of a polyethylene resin composition in which the main component thereof is polyethylene, and an adhesive layer provided between the surface layer and the heat seal layer, wherein the polyamide resin composition is mixed with 0.05 to 1 parts by weight of hydrotalcite with respect to 100 parts by weight of the polyamide resin which is composed of at least one of a nylon ll and a nylon 12. The polyamide resin enables rapid heat-seal under a high-temperature, however hot water resistance of the polyamide resin may sometimes cause problems. The present invention can provide a film for an infusion bag, wherein an elution material is reduced in a pH test, and which has excellent hot water resistance in spite of including the polyamide resin composition in the surface layer thereof, and the infusion bag using the film for the infusion bag.一種輸液袋用薄膜,其係具有:由聚醯胺樹脂組成物所構成之表面層;由以聚乙烯為主成分的聚乙烯樹脂組成物所構成之熱封層;及設於表面層與熱封層之間的接著層之輸液袋用薄膜,聚醯胺樹脂組成物,相對於由尼龍11及尼龍12中1種以上所構成的聚醯胺樹脂100質量份,摻有0.05~1質量份的水滑石而成。本發明係以提供一種儘管將可在高溫下、短時間內進行熱封但耐熱水性有時會成問題的聚醯胺樹脂使用於表面層,仍可減少pH試驗中的溶出物,亦即耐熱水性高的輸液袋用薄膜、與使用輸液袋用薄膜之輸液袋為目的。
