Fastback 11 Supplies

Narrow-width strips are rated for documents up to roughly 125 sheets, but that capacity is based on total stack thickness rather than sheet count alone, so paper weight matters as much as the number of sheets. A 125-sheet document on standard 20 lb bond paper fits comfortably in narrow width, but the same sheet count on heavier stock, like 100 lb photo paper, could measure thick enough to need a medium or wide strip instead. Measure your actual assembled stack thickness rather than relying on sheet count if your document uses anything heavier than standard office paper.

Standard strips, including these Super Strips, are designed for uncoated stock like standard 20 to 28 lb bond paper, and they don't bond reliably to glossy or coated text paper, since the coating creates a barrier that prevents the adhesive from penetrating into the paper fiber. For coated, glossy, or inkjet photo paper, a CP strip is the correct choice instead, since it uses a modified adhesive formulated to bond through that coating. Using a standard strip on coated stock can look fully bonded right after binding but fail later under normal handling.

Color is purely a cosmetic choice and has no effect on adhesive strength or bonding performance, so mixing colors across different documents in the same job or run is fine as long as each document uses a strip sized correctly for its own stack thickness. If you're producing a batch of documents meant to look identical, keeping the color consistent across the batch is a presentation choice rather than a technical requirement.

These narrow Super Strips are built for standard tape binding rather than the composition or hardcover-style finish, which uses a separate strip type with a fabric texture designed to visually match hardcover-style covers. If you're aiming for a book-quality hardcover appearance rather than a standard bound document, a composition strip paired with the appropriate hardcover is the correct combination rather than these standard strips. For the wider Fastback strip lineup across machine types, Fastback binding supplies break down each strip type by compatible machine.
