Abstract: The present invention provides a method for producing polylactic acid-based resin foamed particles for in-mold foam-molding from which a polylactic acid-based resin foam-molded article excellent in heat resistance and mechanical strength can be obtained by in-mold foam-molding. In the method of the present invention for producing polylactic acid-based resin foamed particles for in-mold foam-molding, a rotary blade is rotated at a given rotation speed while being always in contact with the front end surface of a nozzle and a polylactic acid-based resin extrudate extrusion-foamed through a nozzle is cut with the rotary blade, so that it is possible to cut the polylactic acid-based resin extrudate surely to obtain substantially spherical polylactic acid-based resin foamed particles. Therefore, when polylactic acid-based resin foamed particles are used for in-mold foam-molding, the polylactic acid-based resin foamed particles foam uniformly in all directions and, as a result, the foamed particles are thermal fusin bonded to unite together strongly in all direction.

Abstract: A process for producing polylactic acid resin foam particles for in-mold foam forming from which a polylactic acid resin foam molding excelling in heat resistance and mechanical strength can be obtained by in-mold foam forming. In the process for producing polylactic acid resin foam particles for in-mold foam forming, a rotary blade is rotated at a given rotational frequency while constantly keeping contact with the anterior edge surface of a nozzle mold, and the polylactic acid resin extrudate having undergone extrusion foaming from the nozzle mold and foaming is cut by the rotary blade. Accordingly, the polylactic acid resin extrudate can be securely cut to thereby obtain approximately spherical polylactic acid resin foam particles. Therefore, when the polylactic acid resin foam particles are used in in-mold foam forming, foaming of the polylactic acid resin foam particles occurs substantially uniformly in all directions, so that there can be realized mutual strong thermal fusion bonding integration of foam particles in all directions.
