Packaging bag for food and medical packaging bag

摘要

Problem to be solved: to provide a medical packaging bag or a food packaging bag to which an adhesive strength to an annular polyolefin layer is also expressed while maintaining heat resistance while securing heat resistance in a medical packaging bag or a food packaging bag using a laminate comprising an annular polyolefin layer and an adhesive layer.Medical packaging bag or food packaging bag using a laminate having an adhesive layer and an annular polyolefin layer. The adhesive layer comprises the following water block copolymer (I) and propylene based polymer (II).Hydrogenated block copolymers (I): polymeric blocks (a) containing structural units derived from aromatic vinyl compounds Hydrogenation of block copolymers (P) containing a structural block (1) of farnesene derived from 1 to 100 mass% and a polymer block (b) containing structural units (B2) of 99 to 0 mass% derived from conjugated dienes other than farneseneNo selection
