PROBLEM TO BE SOLVED: To provide polyolefinic resin foam particles having solved problems of inferior intra-mold moldabilities and mold shape reproducibilities deemed inherent in polyolefinic resin foam particles having continuous foam structures and a molded artifact of polyolefinic resin foam particles endowed with excellent performances required for foams having continuous foam structures such as flexibility, recovery, sound absorbency, etc. provided by molding the same foam particles.SOLUTION: The provided polyolefinic resin foam particles are polyolefinic resin foam particles wherein mutually adjacent foams of the foam particles possess outer layer portions having foam structures partitioned by foam membrane walls and wherein foam membrane walls of foam particle interiors toward foam particle cores away from the outer layer portions are broken, ruptured, or perforated. |
