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 30×10 4  or more and 100×10 4  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.

Claim (Index 3):
The method for producing polyethylene-based resin foamed particles according to  claim 1 , wherein\n the antioxidant in the polyethylene-based resin composition includes a phosphorus-based antioxidant and a phenol-based antioxidant, and satisfies (a1) and (a2) conditions described below: (a1) a content of the phosphorus-based antioxidant contained in the polyethylene-based resin composition is 500 ppm to 1500 ppm; and (a2) a ratio of a content of the phosphorus-based antioxidant to a content of the phenolbased antioxidant (content of phosphorus-based antioxidant/content of phenol-based antioxidant) contained in the polyethylene-based resin composition is 2.0 to 7.5.
