POLYOLEFIN RESIN FOAM PARTICLES, AND POLYOLEFIN RESIN IN-MOLD EXPANSION MOLDED ARTICLE

摘要

The purpose of the present invention is to produce: polyolefin resin foam particles each of which has a large cell diameter in spite of a fact that the particles are produced using a polyolefin resin having an inorganic anti-blocking agent added thereto such as a polyolefin resin for films; and a polyolefin resin in-mold expansion molded article which comprises the polyolefin resin foam particles and has excellent beauty of the surface thereof. Provided are polyolefin resin foam particles which can be produced by expanding polyolefin resin particles each comprising a polyolefin resin composition and which have an average cell diameter of 100 to 400 μm inclusive, wherein the polyolefin resin composition contains at least two types of inorganic anti-blocking agents in the total amount of 0.03 to 2 parts by weight inclusive relative to 100 parts by weight of a polyolefin resin.
