MASKING FILMS

摘要

Masking films comprise a transparent base, preferably a polyester or a polycarbonate, directly carrying a masking film in the form of a dyed transparent plastics material based upon a vinyl chloride-vinyl acetate copolymer coating, which contains an aromatic polyester-based polyurethane. The amount of vinyl acetate and polyurethane in the coating preferably comprises 30% to 65% w/w of its total polymer content.
