摘要： A process for preparing a two-ply foam molded article, characterized by heating a foamable polyolefin sheet which is in its not yet foamed state to form a foamed polyolefin layer, integrally laminating a fabric on one side of the resulting foamed polyolefin layer which is still in a melted and softened state to form a laminate and simultaneously draw-forming the resulting laminate to shape the two-ply foam molded article.
