<P>PROBLEM TO BE SOLVED: To provide a soft polypropylene-based resin composition which does not practically contain oils like process oil in its resin component, has a moderate flexibility, is excellent in oil resistance to fats and oils. <P>SOLUTION: The soft polypropylene-based resin composition includes 30-100 pts.wt. of a specific thermoplastic elastomer (β) having a high melting peak temperature (Tm) and the like and 100 pts.wt. of a propylene-ethylene block copolymer (α) meeting four conditions including a condition that the copolymer is obtained by sequential polymerization using a metallocene catalyst. <P>COPYRIGHT: (C)2013,JPO&INPIT |
