[Problem] In addition to the suppression of adhesion of components derived from the polymer type antistatic agent to the packaged material, the antistatic performance is excellent, and the rigidity is high, thereby providing a foam sheet having good handling properties and a slip sheet using the same. [Solutions] The multi-layer foam sheet of the present invention is a multi-layer foam sheet having a polystyrene resin foam layer and a polyolefin-based resin layer laminated on at least one side of the foam layer, wherein the resin layer is located on the outermost side of the sheet. And a surface layer to be laminated and adhered to the surface layer, the surface layer contains a polyolefin resin, and substantially does not contain a polymer antistatic agent, and the intermediate layer contains a polyolefin resin and a polymer antistatic agent. It is characterized in that the thickness of the surface layer is 2 to 20 µm, and the surface resistivity of the multi-layered foam sheet on the resin layer stacking side is less than 1.0×10 13 Ω. |
