    Abstract: Polyethylene-based resin foamed particles are obtained having good productivity, achieve an increase in foaming ratio, and in which a miniaturization of the average cell diameter is suppressed. A polyethylene-based resin in-mold-foam-molded body using the foamed particles is reduced in yellowing of the surface of the molded body and has favorable surface beauty (surface smoothness). The foamed particles contain, as a base resin, a polyethylene-based resin composition containing 1000 ppm or more and 4000 ppm or less in total of one or more compounds selected from the group consisting of antioxidants, metal stearates, and inorganic substances and 50 ppm or more and 20000 ppm or less of hydrophilic compounds, in which the Z average molecular weight is 30×104 or more and 100×104 or less, the surface layer film thickness is 11 μm or more and 120 μm or less, and the open-cell ratio is 12% or less.

    Abstract: Provided are pre-expanded polypropylene resin particles having a dimensional expansion coefficient of 1.5% or more determined with a thermomechanical analyzer at a constant compressive load of 1 mg during heating from 30° C. to 100° C. at a temperature increase rate of 10° C./min. Using the pre-expanded polypropylene resin particles can yield an in-mold foam molded product of polypropylene resin having few wrinkles and small dimensional shrinkage without pretreatment such as internal pressure application or compression packing during packing the pre-expanded particles in a mold for in-mold foam molding.
