PURPOSE:To obtain the subject molded article having remarkably improved bulk density and cushioning characteristics and useful as a cushioning material, etc., by firmly welding a number of foamed polyolefin resin particles in a state leaving spaces between the particles. CONSTITUTION:The objective molded article is composed of a number of foamed polyolefin resin particles 1 welded with each other at the surface to form a prescribed shape, wherein the particles are welded with each other at the contacting part formed by the aggregation of the particles having nearly spherical form and the particles are firmly welded in a state leaving spaces 2 between the particles. The surface welding of the foamed particles 1 is preferably carried out by using a binder consisting of a polyolefin resin having a melting point lower than that of the base resin of the foamed particle by 5-30 deg.C, and attached to the surface of the particle 1. |
