Abstract
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.
