By causing polyethylene resin particles, which use a linear low-density polyethylene resin as the base resin, to foam, said linear low-density polyethylene resin being a copolymer of ethylene and an alpha-olefin with 6 and/or 8 carbons, a density of 0.920 g/cm 3 to less than 0.940 g/cm 3 , a melt flow rate (MFR) of 0.1 g/10 minutes to 5.0 g/10 minutes, and a molecular weight distribution (Mw/Mn) of 3 to less than 5, as measured by measured by gel permeation chromatography (GPC), polyethylene resin foam molded articles with beautiful surfaces and low shrinkage rates versus mold dimensions can be manufactured at a wide range of vapor pressures at which excellent molded articles can be obtained during molding, and polyethylene resin foamed particles, which have an average foam diameter of 200 μm to 700 μm, and an open cell rate of at least 12%, can be provided. |
