Fastback Strips

Choose LX strips when the work is being produced on the Fastback 9 and the document may need limited edits after binding. LX strips support reopening and rebinding up to two times, which helps when a corrected sheet may need to be added later. Super strips serve a different workflow. They are designed for Fastback 20, 15xs, and 11 machines and are permanent after binding. They should not be treated as substitutes just because the color or length looks similar. If the machine is a Fastback 9, review Fastback LX strips before choosing colors, widths, and pack quantities. If the machine is not a Fastback 9, verify the correct strip family first.

CP strips make more sense when the document uses coated, glossy, matte-coated, photo, or other hard-to-bind paper. Standard adhesive works best when it can bond into paper fibers. Coated paper can block that bond and cause sheets to release after the spine looks finished. CP strips use a higher-tack adhesive made to penetrate coating and reach the fiber beneath. Catalogs, photo-heavy reports, premium brochures, and coated presentation documents should be checked before supplies are ordered. If the paper surface feels smooth, glossy, or reflective, compare Fastback CP strips rather than assuming a standard strip will hold through repeated handling, especially for customer-facing books.

Choose strip width by compressed spine thickness, not only by sheet count. Paper weight, covers, coated sheets, inserts, and tabs all change the thickness of the finished book. A strip that is too narrow may not hold the full stack securely. A strip that is too wide can leave a bulky or less polished spine, though using wider than needed is safer than under-sizing when the document is near a limit. Bind a real sample before ordering large quantities. Use the same paper, covers, and inserts the team will use in production. Check that the sheets are square, the strip wraps cleanly, and the spine feels secure after cooling.

Weak Fastback binding usually comes from the wrong strip type, wrong width, incompatible paper, poor spine alignment, or incorrect handling after the cycle. A strip that does not match the machine can fail even if it looks similar. Coated or glossy sheets may need CP strips because standard adhesive may not bond through the coating. A stack that is not a jogged square can leave uneven glue contact along the spine. Handling the book too soon can also affect the bond. For mixed Fastback work, keep Fastback binding supplies separated by machine, strip family, width, and paper type so operators do not grab the wrong box during production.
