Abstract: A method of manufacturing a polyolefin foam sheet composition includes extruding a polyolefin sheet, irradiating the extruded sheet to obtain a physically crosslinked sheet, foaming the physically crosslinked sheet with heat to obtain a foamed layer, and skiving the foamed layer to obtain a foam sheet with at least one skived surface. The surface roughness of the skived surface of the foam sheet is different from the surface roughness of an unskived surface.
