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.

摘要： The multilayer foam sheet includes a polyethylene resin foam layer and a resin layer laminated on at least one of the two surfaces of the foam layer. The resin layer has a multilayer structure formed from a surface layer and an intermediate layer. Both the surface layer and the intermediate layer contain a polyethylene resin and a polymeric antistatic agent. The polymeric antistatic agent is contained in the intermediate layer at a proportion of 30-70 wt % (inclusive). The polymeric antistatic agent is contained in the surface layer at a proportion of at least 5 wt % to less than 30 wt %.

摘要： A method for producing a multi-layer foam sheet having a foam layer and a resin layer laminated on at least one side of the foam layer, includes coextruding a foamable molten resin composition which contains a low density polyethylene and a physical blowing agent and a molten resin composition which contains 80 to 20% by weight of a specific ethylene-propylene random copolymer and 20 to 80% by weight of a specific polyethylene resin so that the foamable molten resin composition forms the foam layer and the molten resin composition forms the resin layer.
