description The present invention discloses a polypropylene composition. A resin matrix is composed of copolymerized polypropylene and branched polyethylene with special parameters, such that the resin matrix has a low crystallization tendency, thereby improving spraying adhesion of a surface of the resin matrix. A polyolefin elastomer (POE) in bimodal distribution is further used to improve the appearance after molding.
