A film for a liquid packaging container, comprising at least one of a layer containing a resin composition (X) containing a polypropylene resin (a) and at least one of a hydrogenated block copolymer (b), the hydrogenated block copolymer (b) being a hydrogenated product of a block copolymer containing a polymer block (A) mainly containing an aromatic vinyl compound unit, and a polymer block (B) mainly containing an isoprene (Ip) unit, a butadiene (Bd) unit, or isoprene (Ip) and butadiene (Bd) units, in the resin composition (X), the hydrogenated block copolymer (b) having a phase separation structure having formed therein both (i) an island phase having a long axis of 1 μm or more, or a bicontinuous structure, and (ii) an island phase having a long axis of 300 nm or less, and in the resin composition (X), the mass ratio ((a)/((a)+(b))) of the polypropylene resin (a) and the hydrogenated block copolymer (b) being from 61/100 to 95/100. |
