The shelf liner is a multi-layered thermoplastic composite sheet of consistent thickness, with a non-slip bottom side and a decorative top side. A decorative top sheet is fused to a top surface of a substrate layer. The substrate layer comprises a nonwoven fabric or material that is coated on both sides, and can be fully impregnated, with a foamed plasticized polyvinyl chloride. The foamed plasticized polyvinyl chloride coating on the bottom side of the substrate layer gives the shelf liner a non-slip characteristic. An interlayer of polyvinyl chloride plastisol is disposed between the top sheet and the substrate to enhance the fused bonding of the layers. A bottom surface of the substrate layer may be fully or partly covered with a bottom coating to modify the non-slip nature of the shelf liner.

1. Field of the Invention
The present invention relates to decorative non-slip liners, and more specifically to a shelf liner that comprises a polyvinyl chloride (PVC) top layer laminated or fused to a non-slip bottom layer via a PVC plastisol interlayer. The non-slip bottom layer consists of a non-woven fabric coated on both sides with foamed plasticized polyvinyl chloride.
2. Description of the Related Art
FIG. 1 is a plan view of a shelf liner according to the present invention, with a top layer of the shelf liner cut away to show a substrate layer.
FIG. 2A is a section view drawn along lines 2A-2A of FIG. 1, showing the layered construction of a shelf liner according to the present invention.
FIG. 2B is a section view similar to FIG. 2A showing the layered construction of a first alternate embodiment of a shelf liner according to the present invention.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
The present invention is a shelf liner, designated generally as 10 in the drawings. The shelf liner 10 is formed primarily of layers of plasticized polyvinyl chloride materials, fused together to form a durable liner with a non-skid bottom surface and a decorative and protective top surface. The shelf liner is illustrated in FIG. 1, with a top sheet 20 cut-away to show a foamed plasticized polyvinyl chloride substrate layer 40.
Turning now to FIGS. 2A-2C, the layers of the shelf liner 10 can be seen in greater detail. The substrate layer 40 has a top surface 42 and a bottom surface 44. The top sheet 20 comprises a thin polyvinyl chloride film 22 having top and bottom surfaces 24,26, and optionally a decorative coating 28. In use, the shelf liner 10 is placed on an application surface 12, such as a desk, shelf, countertop, etc., with the substrate bottom surface 44 in contact with the application surface 12. Because of the somewhat tacky, frictionalized nature of the surfaces of the foamed plasticized polyvinyl chloride material of the substrate layer 40, the substrate bottom surface 44 has a non-slip characteristic, giving the shelf liner 10 the tendency to resist movement in the plane of the substrate bottom surface 44 when the substrate bottom surface 44 contacts the application surface 12.
