摘要

Compactibility is satisfactory, the polypropylene resin composition where you can obtain the film or the seat which possesses transparency and the heat seal characteristic which are superior is offered. As for the polypropylene resin composition of this invention, the fusion point Tm which is measured the differential scan calorimeter (DSC) by propylene polymer (A)1 above the 150C - 50 weight %, the propylene copolymer (B)10 where fusion point Tm is under the 150C above the 100C - 90 weight %, the inside either the constitution unit of propylene origin or the constitution units of 1- butene origin one or more where (a) 50 mols % above and, (b) the aforementioned constitution unit (a) being other than, carbon count is chosen one side from the constitution unit of - olefin origin 2 - 20 50 mols % below (here (a) with (b) as for total100 mols %) with it consists of, the olefin copolymer (C)1 where fusion point is under the 100C above the 40C - 80 weight % it is the polypropylene resin composition which consists of. The film which is obtained from this resin composition is ideal as a film for packing such as food.
