Resin composition, heat sealant, film for liquid packaging container, liquid packaging container, liquid discharge member and medical container

摘要

Provided a resin composition capable of providing a liquid packaging container having both high flexibility and low-temperature impact resistance, excellent low-temperature heat seal strength and excellent bag breaking strength, and heat comprising the resin composition A sealing agent and a liquid packaging container film are provided, and the liquid packaging container formed from the liquid packaging container film, the liquid packaging container and the liquid discharge member obtained by using the resin composition, and the liquid packaging container are provided. Provide medical containers. Specifically, the resin composition is a resin composition containing a polypropylene resin (a) and a hydrogenated block copolymer (b), wherein the hydrogenated block copolymer (b) Mainly composed of a polymer block (A) mainly composed of a structural unit derived from an aromatic vinyl compound and a structural unit derived from isoprene, a structural unit derived from butadiene, or a structural unit derived from a mixture of isoprene and butadiene. A hydrogenated block copolymer containing a polymer block (B), the hydrogenated block copolymer (b) has a glass transition temperature of −50 to −35 ° C., and the polypropylene Tensile shear adhesive strength measured according to JIS K 6850 (1999) when the base resin (a) is an adherend and the hydrogenated block copolymer (b) is an adhesive layer is 1.0M. A resin composition is not less than a.
