3M 845 Book Tape is a tough crystal-clear transparent tape with a long-aging, synthetic adhesive that conforms readily to book contours and flexes with cover movements. Excellent for repairing, reinforcing, protecting and covering bound edges and surfaces. Use on books, magazines, pamphlets, record album jackets and more. The transparent polypropylene backing has excellent clarity which doesn't hide title information or printing and saves time and money by eliminating relabeling. It is tough, flexible, resists abrasion
and cracking, and is conformable which reduces rebinding or replacement costs. Its synthetic adhesive is long aging and will not discolor or dry out so it won't deteriorate with time causing
possible subsequent repair.
