A film for a liquid packaging container having at least one layer comprising a polypropylene resin (a) and a resin composition (X) containing at least one hydrogenated block copolymer (b), wherein the hydrogenated block copolymer (b) is a polymer block (A) mainly composed of an aromatic vinyl compound unit, and a polymer block mainly composed of an isoprene (Ip) unit, a butadiene (Bd) unit, or an isoprene (Ip) and butadiene (Bd) unit ( It is a hydrogenated product of a block copolymer containing B), and in the resin composition (X), the hydrogenated block copolymer (b) has (i) an island-like or air-fluid structure with a long axis of 1 μm or more, and (ii) a long axis of 300 nm or less. It has a phase-separated structure forming both island-like structures of, and in the resin composition (X), the mass ratio of the polypropylene resin (a) and the hydrogenated block copolymer (b) [(a)/{(a ) + (B)}] is 61/100 to 95/100, the film for a liquid packaging container. |
