ABSTRACT Disclosed herein is pre-foamed particles of an uncrosslinked linear low-density polyethylene having a crystalline structure characterized in that two endothermic peaks appear on a DSC curve obtained by differential scanning calorimetry of the pre-foamed particles (said DSC curve having been obtained by heating 1-5 mg of the pre-foamed particles to 220°C at a rate of 10°C/min by a differential scanning calorimeter) and the energy at the endothermic peak on the higher-temperature side is 5 J/g or more. A process for the production of the pre-foamed particles of the uncrosslinked linear low-density polyethylene is also disclosed.
