ABSTRACT:
Covering a rigid or hard but pliable, smooth surface with a multilayer masking film having a smooth side and an embossed side is disclosed. The smooth side of the masking film is in direct contact with the smooth surface being covered. Adhesion of the smooth side of the masking 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 masking 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.
