What's Included
One 50mm x 13.7m roll of Scotch 845 Book Tape. No dispenser is included — the tape is thick and durable by design, so it needs to be cut with scissors or a blade rather than torn by hand.
Why Choose This Roll
This is genuine Scotch-branded 3M tape, not a generic re-labelled equivalent — the same product libraries, schools and print shops rely on for everyday book and document repair. The acrylic adhesive is designed to stay flexible and hold without drying out or cracking, so a repair made today should still be holding well down the track. One roll goes a long way: 13.7m of tape covers dozens of individual spine, cover or hinge repairs, depending on book size and how much overlap you use.
What is Scotch 845 Book Tape used for?
It repairs, reinforces and protects the spines, covers and hinges of paperback and hardcover books, plus folders and documents.
Is this the same as regular sticky tape, like Scotch Magic Tape?
No — Scotch 845 is a heavier-duty polypropylene tape built for book repair, while Scotch Magic Tape (810) is a thinner, general-purpose paper tape.
Will this tape go yellow or brittle over time?
The acrylic adhesive is designed to stay clear and flexible rather than yellowing or cracking, though it's not marketed as archival or acid-free — check with a conservation specialist for rare books.
Can I tear this tape by hand, or do I need scissors?
You'll need scissors or a blade — the polypropylene backing is thick and tough by design, so it won't tear cleanly like household sticky tape.
Is this suitable for both paperback and hardcover books?
Yes, it suits both; for delicate repairs like a torn page or fragile dust jacket, a lighter or archival-grade tape is usually a better fit.
How much can one roll cover?
One roll gives you 13.7m of 50mm-wide tape — enough for dozens of spine, cover or hinge repairs, depending on book size.
Is this genuine 3M Scotch tape?
Yes — this is genuine Scotch-branded tape made by 3M, not a generic or re-labelled substitute.
Do you stock other sizes of this tape?
Yes — Ink and Rolls also stocks a 36mm x 13.7m Scotch 845 Book Tape for smaller repairs or thinner spines.
