Provided is a production method for polyethylene-based resin extruded foam sheets, in which: a foamable molten resin composition comprising a low-density polyethylene, a physical foaming agent, and an antistatic agent that have been kneaded is extruded and foamed; and polyethylene-based resin extruded foam sheets are formed. The production method for polyethylene-based resin extruded foam sheets is characterized: by the thickness of the foam sheets being 0.05-0.5 mm; and by, using as the antistatic agent, a polymeric antistatic agent that has a melting point within -10-10°C of the low-density polyethylene melting point and a melt flow rate of at least 10 g/10 mins. As a result, a novel polyethylene-based resin extruded foam sheet can be obtained that, regardless of being extremely thin, is high quality, has excellent strength and shock-absorbing properties, prevents/suppresses generation of fine pores or through-holes even after medium to long-term continuous production, exhibits sufficient antistatic properties, and is suitable as an interleaving paper for glass plates. |
