POLYOLEFIN FILM FOR USE AS A NON-STAINING MASKING FILM

摘要

Synthetic polyolefin films of one or more layers, wherein each layer may be of a different thickness and a different formulation. The films consist of a polyolefin resin and a suitable mineral filler of at least three microns in particle size. The films are particularly useful as a masking material in paint overspray protection systems and may be used to protect a finished surface from moisture and/or ultraviolet radiation. The films possess the advantage that their use does not result in staining or ghosting on the protected or masked surface.
