ABSTRACT:
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.
