    摘要: Provided is a polypropylene resin composition having excellent impact resistance, impact strength at low temperature and transparence comprising ethylene-alpha olefin copolymer (c) to a polypropylene resin composition in which the ratio of viscosity is regulated by adjusting molecular weight of propylene-alpha olefin random copolymer (a) and propylene-alpha olefin elastic copolymer (b), thereby regulating impact resistance and flexural modulus of the polypropylene resin composition and improving transparence; therefore, applying as various products including cold-storage containers for freezer and refrigerator, food packaging container, extrusion blow molding material, film, sheet and bottle cap, etc.
