PURPOSE: A polypropylene resin composition for a protection film is provided to generate low amounts of fisheyes, to have high transparency, and to have excellent durability and cuttability. CONSTITUTION: A polypropylene resin composition for a protection film includes a propylene homopolymer and an ethylene-propylene rubber blend resin. The comprised amount of the ethylene-propylene rubber is 5-30 weight% with reference to the blend resin. The ethylene content in the ethylene-propylene is 45 mol% or less based on an ethylene content in a solvent extraction solvent. The molecular weight distribution of the blend resin is 2.5-3.8 based on the polydispersity index thereof. The inherent viscosity of the solvent extraction rubber is 1.5 dl/g or less. |
