A
Abstract:
PURPOSE: To provide a method for retrieving foamed particles having no damage from a foamed particle molded body easily and with a high yield.
CONSTITUTION: A foamed particle fusion surface is fused or a fine crack is generated on a foamed particle molded body having a thermoplastic resin as a base material so as to weaken sticking force among particles.
