GF 111 is a 2.0 mil clear polypropylene film coated with a permanent acrylic pressure sensitive adhesive on a smooth paper liner. This laminate can turn any printed graphics into a writeable dry erase surface and is designed for use with dry erase markers. GF 111 is best suited for short-term or promotional indoor graphics, where long-term durability is not required. See the General Formulations website for other longer-term products such as GF 110 EraseMark Pro™.
