PROBLEM TO BE SOLVED: To provide a water-soluble film for medicine packaging that reduces curling in forming a packaging body with a film having been stored for a long period and thereby hardly causes a position shift to have superior productivity, and that is small in area variation rate with time even in a state in which the package body has a liquid such as a liquid detergent packaged, so that tension of the water-soluble film is not spoiled.SOLUTION: There is provided a water-soluble film for medicine packaging which contains a polyvinyl alcohol-based resin (A) and a plasticizer (B), the water-soluble film for medicine packaging being characterized in that the plasticizer (B) contains a compound expressed by general formula (1), where 1≤a≤4 (a: a positive integer), 1≤b≤4 (b: a positive integer), m≥1, n≥1, and 2≤m+n≤7 (m, n: positive integers).SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】長期間保管したフィルムで包装体を形成する際のカールが軽減され、それ故、位置ずれが起こりにくく、生産性に優れたものであり、かつ液体洗剤などの液体を包装して包装体とした状態であっても経時で面積変化率が小さいため、水溶性フィルムの張りを損なわない薬剤包装用水溶性フィルムを提供する【解決手段】ポリビニルアルコール系樹脂（Ａ）及び可塑剤（Ｂ）を含有してなる薬剤包装用水溶性フィルムであって、可塑剤（Ｂ）が、下記一般式（１）で示される化合物を含有することを特徴とする薬剤包装用水溶性フィルム。［式中、１≦ａ≦４（ａは正の整数）、１≦ｂ≦４（ｂは正の整数）、ｍ≧１、ｎ≧１、かつ２≦ｍ＋ｎ≦７（ｍ，ｎは正の整数）を満足する。］【選択図】なし
