PROBLEM TO BE SOLVED: To provide a film for a liquid packaging container that is transparent and has both flexibility and strength against bag rupture at a low temperature (at around -10 to 10°C, for example), a liquid packaging container using the same, and a medical instrument.SOLUTION: The present invention relates to a film for a liquid packaging container which has at least one layer consisting of a resin composition (X) containing a polypropylene resin (a), an α-olefin copolymer (b), a hydrogenated block copolymer (c), and a hydrogenated block copolymer (d), wherein the hydrogenated block copolymer (c) and the hydrogenated block copolymer (d) are each independently a hydrogen additive of a block copolymer including a polymer block (A) consisting principally of an aromatic vinyl compound-derived structural unit and a polymer block (B) consisting principally of one kind or more selected from an isoprene-derived structural unit and a butadiene-derived structural unit; a glass transition point (Tgc) derived from the polymer block (B) of the hydrogenated block copolymer (c) and a glass transition point (Tgd) derived from the polymer block (B) of the hydrogenated block copolymer (d) satisfy an expression (1) of -60°C≤(Tgd)<;(Tgc)≤-10°C; and the mass ratio [(a)/{(a)+(b)+(c)+(d)}] of the polypropylene resin (a) to the total of the polypropylene resin (a), the α-olefin copolymer (b), the hydrogenated block copolymer (c), and the hydrogenated block copolymer (d) is 51/100 to 95/100.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】透明性を有すると共に、柔軟性と低温(例えば-10℃~10℃程度)における破袋強度とを兼ね備える液体包装容器用フィルム、これを用いた液体包装容器、及び医療用具を提供する。【解決手段】ポリプロピレン系樹脂(a)、α-オレフィン共重合体(b)、水添ブロック共重合体(c)及び水添ブロック共重合体(d)を含有する樹脂組成物(X)からなる層を少なくとも1層有する包装容器用フィルムであって、 前記水添ブロック共重合体(c)及び前記水添ブロック共重合体(d)が、それぞれ独立に、芳香族ビニル化合物由来の構造単位を主体とする重合体ブロック(A)と、イソプレン由来の構造単位、及びブタジエン由来の構造単位から選ばれる1種以上を主体とする重合体ブロック(B)とを含むブロック共重合体の水素添加物であり、 前記水添ブロック共重合体(c)の重合体ブロック(B)に由来するガラス転移点(Tgc)及び前記水添ブロック共重合体(d)の重合体ブロック(B)に由来するガラス転移点(Tgd)が下記式
