Tabbing Services
Sealed Right. Mailed Compliant.
USPS-compliant wafer seal tabs applied to self-mailers and folded pieces — keeping them closed for postal processing.
What Is Tabbing Services?
Tabbing machines apply small adhesive wafer seals (typically 1-inch or 1.5-inch round or rectangular tabs) to the open edges of folded self-mailers. USPS requires these tabs to prevent the open edge from catching in postal processing equipment. Without proper tabbing, self-mailers may be rejected at the post office or charged non-automation rates.
Tabbing is the application of small adhesive wafer seals (tabs) to folded self-mailers, brochures, and newsletters to hold them closed during USPS processing. USPS requires tabs on most self-mailers that do not use envelopes. Catdi Printing applies tabs as part of the mail finishing workflow — ensuring your self-mailer qualifies for automation postage rates.
