摘要

Foamed particles having a polypropylene resin (X) including a polypropylene resin (I) having a melting point of 145-165°C and a high-density polyethylene resin (II) having a density of 0.93-0.97 g/cm³ as the base resin, characterized in that the polypropylene resin foamed particles contain one or fewer foam nucleating agents relative to the polypropylene resin (X).
