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. |
