PURPOSE:To obtain the titled composition having heat-sealability, printability and blocking resistance without deteriorating transparency, etc., and suitable for automatic packaging, etc., by compounding a polypropylene with a specific amount of a hydrogenated thermally copolymerized resin produced from a chain alpha-olefin and cyclophentadienes. CONSTITUTION:The objective composition can be produced by compounding (A) 70-99pts.wt., preferably 70-95pts.wt. of polypropylene with (B) 1-30pts.wt., preferably 5-30pts.wt. of a hydrogenated product of a thermally copolymerized resin of a chain alpha-olefin and cyclopentadienes and having a hydrogenation ratio of 60-100% and produced by thermally copolymerizing (B1) 100pts.wt. of cyclopentadienes and (B2) 5-100pts.wt. of a 4-16C chain alpha-olefin and hydrogenating the obtained resin.
