POLYPROPYLENE COMPOSITION AND POLYPROPYLENE MULTILAYER FILM USING THEREOF

摘要

PURPOSE: A polypropylene resin composition is provided to have excellent low temperature impact strength at cool storage while maintaining transparency, heat resistance and thermal adhesion. CONSTITUTION: A polypropylene resin composition comprises an ethylene-propylene random-block copolymer. The ethylene-propylene random copolymer comprises 75-95 weight% of an ethylene-propylene random copolymer with an ethylene content of 0.5-5 weight5 and 20-50 weight% of an elastic ethylene-propylene block copolymer. The ethylene-propylene random-block copolymer has an absolute viscosity of 0.5-2.5 dl/g and a melt index of 1-10 g/10minutes under the load of 2.16kg and the melt index of 230 deg. C.
