1. A self-wound roll of pressure sensitive adhesive surface covering comprising:

  • (a) a laminate having two surfaces, said laminate consisting essentially of;

    (i) a substrate layer having a first surface and a second surface, said substrate layer comprising a polymeric film comprising a vinyl- or vinylidene halide homopolymer or copolymer;

    (ii) a first stabilizing layer adhered to said first surface of said substrate layer, said first stabilizing layer comprising a polymeric film comprising a polyolefin or a polyester; and

    (iii) an optional second stabilizing layer adhered to said second surface of said substrate layer, said stabilizing layer comprising a polymeric film comprising a polyolefin or a polyester;

    (b) a pressure sensitive adhesive layer on one surface of said laminate; and

    (c) a release layer on the other surface of said laminate, said release layer consisting of a transparent flexible synthetic resin material having release properties with respect to said pressure sensitive adhesive layer;

    wherein said self-wound roll includes a plurality of turns of said pressure sensitive adhesive surface covering such that said release layer (c) on one turn is in contact with said pressure sensitive adhesive layer (b) on an adjacent turn, said release layer after storage for 7 days at 158°
