PROBLEM TO BE SOLVED: To provide a resin composition superior in flexibility and cushioning properties and excellent in heat resistance (retort resistance), oil resistance and molding processability and more particularly a resin composition useful as a liner material for a lid for a container, especially as a liner material suitable for an inshell mold. SOLUTION: A resin composition comprises (1) 100 pts.wt. block copolymer produced by hydrogenating a block copolymer comprising at least two polymer blocks A derived mainly from a vinyl aromatic compound and at least one polymer block B derived mainly from a conjugated diene compound, which has a number average molecular weight of not less than 100,000, (2) 5-50 pts.wt. propylene polymer and/or copolymer having a melt flow rate (measured according to JIS K7210, under a load of 2,160 g, at a temperature of 230 deg.C) of not less than 10 g/10 min and (3) 5-50 pts.wt. polypropylene-ethylene/propylene copolymer having a melting point of not less than 135 deg.C, wherein the total of the content of the component (2) and the component (3) is in the range of 20-90 pts.wt. |
