Title:
LIQUID PACKAGING CONTAINER
Document Type and Number:
Japanese Patent JP2016155604
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid packaging container that has excellent flexibility and transparency, high heat seal strength, high bag breaking strength at room temperature and low temperature, and has low inner layer agglutination, which are important as a medical liquid packaging container.SOLUTION: A liquid packaging container is formed of a laminate including at least three layers of an inner layer (Y), a middle layer and an outer layer (Z), and the middle layer is formed of (X). (X) is a resin composition containing 100 pts.mass of a polypropylene-based resin, 5-95 pts.mass of a specific thermoplastic elastomer, and 10-95 pts.mass of a specific ethylene-α-olefin copolymer. (Y) is a resin composition containing 100 pts.mass of a polypropylene-based resin, and 5-250 pts.mass of a specific thermoplastic elastomer (where resin composition contains no specific ethylene-α-olefin copolymer or contains less than 10 pts.mass of specific ethylene-α-olefin copolymer). (Z) is a resin composition containing 100 pts.mass of a polypropylene-based resin and 0-35 pts.mass of a specific thermoplastic elastomer.SELECTED DRAWING: Figure 1
