摘要： A laminated foam sheet having a polyethylene resin foam layer and an antistatic polyethylene layer laminated on one or both sides thereof is produced by coextruding melts for respective layers, wherein the melt for the antistatic layer contains a polyethylene resin, an ionomer resin antistatic agent and a specific amount of volatile plasticizer blend containing an alcohol and a saturated hydrocarbon or a dialkyl ether. The antistatic layer of the obtained laminated foam sheet has specific morphology.
