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. Widths shown in dropdown are in inches. NOTES: Sizes shipped will typically be the tape industry standard metric-cut sizes, i.e. 24mm for each 1 inch of nominal tape width ordered (rolls are approximately 5% narrower than the nominal size). This product's actual size is 36mm x 13.7m.
I can't exactly figure out how this is different from just plain old packaging tape though. It looks exactly the same. I can't see where it says it is acid or lignin free.
Do note that it comes without a dispenser and is a bit clumsy to use without one (just as packing tape is)
