Summary: | A polyolefin type resinous composition comprising 99 to 80% by weight of a propylene type block copolymer ÄAÜ and 1 to 20% by weight of an ethylene type or styrene type elastomer ÄBÜ which being superior in a transparency, a coloring property and a dimensional stability is provided. The said polyolefin composition comprises the said ÄAÜ consisting of a propylene homopolymer component and an ethylene-propylene copolymer component having respective limiting viscosities: Ä eta ÜPP, Ä eta ÜRC, weight %: WPP, WRC, and melt flow rates: ÄMFRÜPP, ÄMFRÜRC, as well as the said ÄBÜ having a limiting viscosity: Ä eta ÜR and a melt flow rate: ÄMFRÜR, in such a way that the following relationships being established; |
