Provided is a liquid packaging container having satisfactory flexibility and transparency, high heat-seal strength, high bag-breaking strength at normal temperature and low temperatures, and low (inner layer)-(inner layer) adhesiveness, which are properties important for liquid packaging containers for medical use. Specifically, provided is a liquid packaging container formed from a laminate of at least three layers including an inner layer formed from a resin composition (Y) as described below, an intermediate layer, and an outer layer formed from a resin composition (Z) as described below, the intermediate layer being formed from a resin composition (X) as described below: resin composition (X): a resin composition including 100 parts by mass of a polypropylene-based resin (1), 5 parts by mass to 95 parts by mass of a particular thermoplastic elastomer (2), and 10 parts by mass to 95 parts by mass of a particular ethylene-±-olefin copolymer (3) resin composition (Y): a resin composition including 100 parts by mass of a polypropylene-based resin (1), and 5 parts by mass to 250 parts by mass of a particular thermoplastic elastomer (2) (provided that a particular ethylene-±-olefin copolymer is not included or, if included, the content of the copolymer is less than 10 parts by mass) and resin composition (Z): a resin composition including 100 parts by mass of a polypropylene-based resin (1"), and 0 parts by mass to 35 parts by mass of a particular thermoplastic elastomer (2").本發明提供一種液體包裝容器,其在作為醫療用之液體包裝容器上重要,且具有良好的柔軟性、透明性、高熱封強度、常溫及低溫時之高破袋強度、以及低內層膠著性。具體而言,提供一種液體包裝容器,其包含積層體,該積層體至少具有3層:包含下述樹脂組成物(Y)之內層、中間層、及包含下述樹脂組成物(Z)之外層,前述中間層包含下述樹脂組成物(X);樹脂組成物(X):係含有100質量份之聚丙烯系樹脂(1)、5~95質量份之特定熱塑性彈性體(2)、以及10~95質量份之特定乙烯-α-烯烴共聚物(3)的樹脂組成物;樹脂組成物(Y):係含有100質量份之聚丙烯系樹脂(1’)、以及5~250質量份之特定熱塑性彈性體(2’)的樹脂組成物,惟不含有特定的乙烯-α-烯烴共聚物,或即使含有亦低於10質量份;樹脂組成物(Z):係含有100質量份之聚丙烯系樹脂(1”)、以及0~35質量份之特定熱塑性彈性體(2”)的樹脂組成物。
