Abstract: A multi-layer foam sheet with an apparent density of 30 to 300 kg/m3 and a thickness of 0.05 to 2 mm, including a foam layer containing a polyethylene-based resin, and an antistatic layer fusion-laminated by coextrusion on each of both sides of the foam layer. The antistatic layer has a basis weight of 1 to 10 g/m2 and contains a polyethylene-based resin, a polystyrene-based resin, a styrenic elastomer, and a polymeric antistatic agent, with the polystyrene-based resin being contained in the antistatic layer in an amount of 15 to 70% by weight.

Abstract: A polyethylene-based resin multilayer foam sheet may include a polyethylene-based resin foam layer containing a polyethylene-based resin (A) as a base resin, and a conductive layer laminated on at least one side of the foam layer. The conductive layer contains: a mixed resin of one or more polyethylenes (B) of low-density polyethylenes and/or linear low-density polyethylenes and an ethylene-based copolymer (C) having a structural unit derived from ethylene and a structural unit derived from a monomer having a polar group; and conductive carbon. The conductive carbon blended in the conductive layer may be in a range of from 3 to 15 wt. %. The difference, TmB−TmC, between the melting point TmB of the polyethylene (B) and the melting point TmC of the ethylene-based copolymer (C) each contained in the conductive layer may be in a range of from 30 to 80° C.
