A liner structure comprising a flexible sheet having a top surface and a bottom surface, said flexible sheet being comprised of a first polymeric resin whic h is sufficiently soft to render the flexible sheet non-curling and the bottom surface non-skid, and a plurality of upwardly extending ridges on the top surface of the flexible sheet, said upwardly extending ridges being comprised of a second polymeric resin which is harder than the first polymeric resin and which provides a low friction surface on the top edges of said upwardly extending ridges. T he liner structures are suitable for use as non-adhesive, non-skid liners to cover and/or protect generally horizontal planar surfaces such as shelves, drawers , and the like and methods of making such structures.
