EXPANDED BEADS, AND EXPANDED BEAD MOLDED BODY

Abstract: an expanded bead containing a linear low-density polyethylene as a base resin, wherein the linear low-density polyethylene has a biomass degree of 40% or more as measured according to astm d 6866; the expanded bead has a crystal structure where a melting peak intrinsic to the linear low-density polyethylene (intrinsic peak) and at least one melting peak on a higher temperature side than the intrinsic peak (high-temperature peak) appear on a dsc curve drawn by heating the expanded bead from 23� c. to 200� c. at a heating rate of 10� c./min; a total heat of fusion of the expanded bead is 70 j/g or more and 100 j/g or less; and a heat of fusion at the high-temperature peak is 10 j/g or more and 50 j/g or less.
