Product Identity

3M 845112 Scotch 845 Book Repair Tape is a clear, conformable tape designed for repairing and reinforcing bound edges and surfaces. It suits librarians, archivists, collectors and anyone preserving books, magazines, pamphlets or record album jackets. The tape accepts most permanent inks for labelling.

Thermal Noise Power

As a passive adhesive product, this tape generates no heat, produces no noise and draws no power during application or long-term use. It requires no external energy source and adds no thermal load to any environment. Performance remains stable without active cooling.

Build Fit

The roll mounts on a standard 3-inch core and unwinds to 15 yards of transparent material. It frees users from specialised dispensing equipment and works with hand-held or desktop dispensers that accept the core size. No additional hardware, software or power connections are needed for operation.

Questions about this item

How do I apply the 845 tape so the 1-1/2 inch width covers a book spine without bubbles?

Clean the surface, align the roll with the spine edge, and press firmly from the centre outward using a folder or finger; the conformable adhesive lets you reposition once before it sets permanently.

Will the 845 tape yellow or need replacing after a few years on a heavily used book?

The adhesive is formulated not to dry out or crack, so the tape remains clear and flexible; replacement is only needed if the book cover itself tears beyond the taped area.

At what point does the 15-yard roll run out during a large repair project?

Each roll supplies 15 yards of 1-1/2 inch wide tape; the limit is simply the length on the 3-inch core, so plan coverage by measuring total spine and edge inches before starting.
