Disclosed is polyolefin resin pre-expanded particles which are produced by foaming polyolefin resin particles formed from a polyolefin resin composition comprising 100 parts by weight of a polyolefin-based resin, less than 0.01 part by weight of a low-molecular type antistatic agent, and 5 parts by weight or more and 30 parts by weight or less of a polyether-polyolefin resin block copolymer-based antistatic agent. The polyolefin resin pre-expanded particles have an antistatic property. In the production of the polyolefin resin pre-expanded particles, the dispersion state of the polyolefin resin particles formed from the polyolefin resin composition in an aqueous dispersion medium is improved compared to conventional particles. Therefore, the productivity rate of the pre-expanded particles can be improved. |
