Abstract: The present disclosure relates to a polypropylene resin composition for improving the surface quality of a molded article and enhancing injection moldability. The polypropylene resin composition of the present disclosure minimizes the shear stress generated in a cavity and has high viscoelasticity, which induces smooth flow of a recycled material and prevents the occurrence of flow marks on the molded article. Additionally, the polypropylene resin composition of the present disclosure may exhibit improved processability and aesthetics during two-shot injection molding.
