Avery Dennison PermaPrint PR800 is a 3-mil intermediate translucent vinyl film for internally illuminated signage such as awnings, light boxes, and channel letters. The translucent colors diffuse transmitted light evenly while reading as opaque vinyl when unlit, and the film cuts and weeds cleanly on sign equipment. It uses a permanent acrylic adhesive on a liner and applies to backlit scrim, glass, polycarbonate, and acrylic faces. Recommended for backlit sign faces, light boxes, and awning graphics with up to 6-year outdoor durability.
