Abstract: The disclosed film backing has a multilayer extensible substrate with a securing adhesive that can secure to a surface and a tab to stretch the extensible substrate to remove the securing adhesive from the underlying surface. Stretching the extensible substrate will easily release the adhesive from the underlying surface. Therefore, a strong adhesive can be used. The multilayer extensible substrate includes an elastic layer forming the core adjacent to a plastically-deforming layers forming the skin to minimize the elasticity of the overall construction.
