摘要：
With use of expanded polypropylene resin particles having, as a base material resin, a polypropylene resin composition X containing a polypropylene resin A having a low melting point, a polypropylene resin B having a high melting point, and a polyethylene resin C having a specific melting point, wherein the polypropylene resin A, the polypropylene resin B, and the polyethylene resin C are present in respective predetermined amounts, a polypropylene resin in-mold expanded molded product having a high compressive strength and an excellent appearance is produced at a decreased molding temperature during in-mold foaming molding.
