POLYOLEFIN RESIN COMPOSITION, FILM, AND MEDICAL BAG AND TUBE

摘要

A polyolefin resin composition including: a polyolefin resin; and a hydrogenated block copolymer having a polymer block A having vinyl aromatic monomer units as a main component thereof, and a polymer block B having conjugated diene monomer units as a main component thereof; the polyolefin resin composition wherein the mass ratio of the polyolefin resin/hydrogenated block copolymer is 95-5 parts by mass/5-95 parts by mass, the total content of vinyl aromatic monomer units in the hydrogenated block copolymer is 12-25% by mass, the hydrogenation rate of double bonds based on conjugated diene monomer units in the hydrogenated block copolymer is 90 mol% or greater, and the melt flow rate is 7-26 g/10 minutes.
