摘要:
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-α-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-α-olefin copolymer is not included or, if included, the content of the copolymer is less than 10 parts by mass) andresin 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″).
