General Formulations 60" x 25' 270 WindowMark Matte Perf 70/30 Window Film

270 is a white pressure sensitive, black back perforated film, coated with a clear removable adhesive. The adhesive is designed for excellent clean removability from glass. The open area is approximately 30% with a hole size of .060 inches (1.5mm). The dual layflat liner raises the film slightly, creating a bucket so ink can move easily through the perforations during the printing process and limit unwanted blockages in the film.
