Abstract
A resin composition containing a propylene-based resin and at least one selected from the group of a rubber material and an elastomer, the rubber material and the elastomer each including at least two units from among ethylene, propylene, butylene, hexene, isoprene, octene, and styrene, the resin composition having a viscosity of 200 Pa·s or more and 5000 Pa·s or less at a high shear rate with a shear rate of 100 s−1 at a temperature of 190° C., and a viscosity of 7000 Pa·s or more and 50000 Pa·s or less at a low shear rate with a shear rate of 1 s−1 at a temperature of 190° C., the resin composition having an elastic modulus of 150 MPa or more and 700 MPa or less.
Claims9
A resin composition comprising
