This is an Eco-friendly self-wound repositionable product that can be used for your direct mail applications. It is a 20# white bond paper with full gum microsphere adhesive and no liner. This allows for easy press set-up and great for processing in laser printers, folders, and inserters. This product can also be used as a backer when laminated to other face stocks that are die-cut, and need to be adhesive free once removed.
