HellermannTyton thermal transfer ribbons are designed for use in HellermannTyton thermal transfer printers. Available on 1/2" and 1" cores, the ribbons are coated side out and available in two different lengths. All ribbons are available in a variety of colors and are matched to the HellermannTyton label stock to give the best chemical and abrasion resistance.
