ABSTRACT:
Covering a rigid but pliable, smooth surface with a one-sided matte embossed polyethylene film, where the non-embossed smooth side of the film is in direct contact with the smooth surface being covered. Adhesion of the smooth side of the film to the smooth surface to which it is applied is effected much like a vacuum adhesion as seen when a drop of water is placed between two sheets of glass. The embossed side of the film forms microscopic air pockets when rolled upon itself which prevents blocking. This feature allows the non-embossed side to be made as smooth as possible without the need for an anti-blocking agent.
