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： The multilayer foam sheet has a surface resistivity of 1×1013Ω or less and has a foam layer and resin layers that are laminated on both surfaces of the foam layer. The resin layers each have a multilayer structure formed from a surface layer and an intermediate layer that is positioned between the surface layer and the foam layer. The foam layer includes a polyethylene-based resin PE2. The intermediate layers are configured from an antistatic mixture containing a polyethylene-based resin PE3 and a polymeric antistatic agent. The surface layers are configured from a mixed resin containing a polyethylene-based resin PE4 and a polystyrene-based resin, and substantially do not contain the polymeric antistatic agent. The polystyrene-based resin content of the mixed resin is 3-35 wt %.

摘要： Provided is a method for producing a polyethylene-based resin extruded foam sheet by extruding and foaming a foamable molten resin composition formed by kneading a mixture containing a low-density polyethylene, a physical blowing agent, and an antistatic agent, wherein the foam sheet has a thickness in a range of from 0.05 to 0.5 mm, and the antistatic agent is a polymeric antistatic agent having a melting point whose different from the melting point of the low-density polyethylene is in a range of from −10 to +10° C., and having a melt flow rate of 10 g/10 min or more. This method enables a novel polyethylene-based resin extruded foam sheet to be obtained that is of high quality such that formation of a small hole or a through-hole has been reduced or eliminated, and has both excellent strength and a shock-absorbing property despite a very small thickness even in medium- or long-term continuous production, and besides, exhibits a sufficient antistatic property, thus suitable as a glass plate interleaf sheet.
