This 25-foot banner is printed on our standard vinyl with a PSL (pressure sensitive laminate) to protect it from the weather. It has been on the side of the Salem State University O’Keefe Center since last Summer and it looks as good today as it did the day they put it up. This combination of materials is an excellent solution for large banners that are going against a wall, fence, or other fairly solid structure. Proper installation is key to its longevity; we don’t put all those grommets in for fun. Our standard vinyl is a 15-mil multi-layered product that prints beautifully, has great opacity and can obviously stand up to the elements.
