Crystal clear edge reinforcement tape is the perfect way to prevent tears on important papers. It is made from rugged, non-yellowing polypropylene with an aggressive acrylic adhesive.
Use it by hand or with an edging machine on sheet music, blue prints, posters or any other paper you want to keep from tearing. Standard widths are 1/2", 3/4" and 1". Custom widths are available as well.
