POLYPROPYLENE RESIN COMPOSITION

摘要

PURPOSE: A polypropylene resin composition is provided to have a low frictional force, facilitate post processes, have a low rate of generating fisheyes, and provides a protection film with high transparency. CONSTITUTION: A polypropylene resin composition includes a blend resin of an ethylene-propylene random copolymer, and an ethylene-propylene rubber. The ethylene content of the ethylene-propylene random copolymer is 0.1-1.5 wt%. The content of the ethylene-propylene rubber is 5-20 wt% based on a solvent extraction rubber (xylene extract). The inherent viscosity of the solvent extraction rubber is 2.0 dl/g or less. The melting index of the blend resin is 1-10 g/10minutes (230°C).
