Abstract:
A method for producing a polyethylene-based resin laminated foam sheet according to the present invention is a method for producing a polyethylene-based resin laminated foam sheet 1 with thickness of 0.05 to 0.5 mm in which an anti-static layer is adhered by lamination on at least one surface of the foam layer, including: a step of performing coextrusion and foaming of a laminate which is obtained by combining and laminating, in a die 10, a melt resin composition 6 for forming a foam layer obtained by kneading a low density polyethylene A and a physical foaming agent and a melt resin composition 9 for forming an anti-static layer obtained by kneading a low density polyethylene B and an anti-static agent, wherein the anti-static agent is a polymeric anti-static agent C which has a melting point to allow a melting point difference in the range of from −10° C. to +10° C. compared to that of the low density polyethylene B and has a melt flow rate of 10 g/10 minutes or more.
