    Abstract: Provided are non-crosslinked foamed polyethylene resin particles that have a bulk density BD of 10 g/L or more and 100 g/L or less and are obtained by foaming polyethylene resin particles containing an antistatic agent in an amount of 0.1 part by weight or more and 3 parts by weight or less with respect to 100 parts by weight of a polyethylene resin and having a density of 0.920 g/cm 3 or more and less than 0.940 g/cm 3 , and the non-crosslinked foamed polyethylene resin particles have a shrinkage ratio of 3% or more and 30% or less determined in accordance with Formula (1). The non-crosslinked foamed polyethylene resin particles can simply afford an antistatic molded non-crosslinked foamed polyethylene resin body that has a small shrinkage ratio with respect to mold dimension, is deformed in a small degree, and has good surface stretch. Shrinkage ratio = (BD-VBD) x 100/VBD (1) In the formula, BD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C and 0.1 MPa (under standard atmospheric pressure), and VBD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C under a reduced pressure of 0.002 MPa or less.

    Abstract: PROBLEM TO BE SOLVED: To obtain an in-mold expansion-molded body that is obtained by filling polypropylene-based resin foamed particles in a mold and by heat-molding with steam, especially which is excellent in the fusion of the foamed particles from low temperatures and which has little deformation in the molded body and little clearance among the constituent particles one another (owing to the high elongation of the expanded particles) and also which is uniformly fused and excellent in the surface properties.
    SOLUTION: The solution found out is such that it is necessary to control the heat shrinkage starting temperature of the expanded particles in order not to cause the degradation of the surface properties and the fusion maldistribution in a molded body and also to use a low melting point polypropylene-based resin in order to mold under a low molding pressure.
