SAG 38 is a 1.5 mil high gloss and ultra-clear, durable polyester face with excellent graffiti, and UV protection. It has an optically clear, acrylic, pressure sensitive adhesive protected by a 1.5 mil smooth PET film release liner. SAG 38 has perfect optical clarity due to its film liner and therefore can be used as an inexpensive overlaminate for perforated window films.
