9 x 12 Catalog Envelopes for Bulk Mailing

These 9 x 12 open-end catalog envelopes come in a box of 500 and use a pressure-sensitive seal that closes without moisture. The 28 lb white sulphite stock is SFI certified with 92% brightness and a vellum finish. They suit offices, fulfilment centres and anyone sending flat documents, catalogues or brochures in high volume.

Pressure-Sensitive Seal Changes the Workflow

The Kwik-Tak flap removes the need for moisteners, tape or peel-off liners, so each envelope seals with a single press. That cuts packing time per piece and eliminates the mess of traditional gummed flaps. The centre seam construction keeps the seal line centred for a cleaner appearance on mailed items.

500-Count Box Handles Large Runs, Not Small Batches

At 22 lbs per box the carton is substantial, so it suits operations that process hundreds of mailpieces per week. Smaller shippers may find the quantity and weight excessive for occasional use. The open-end format fits standard letter and legal sheets without folding, but it does not accommodate thick padded contents.

Questions about this item

Will the pressure-sensitive adhesive lose its seal if the envelopes are stored for a long time?

The Kwik-Tak adhesive is designed for reliable sealing without moisture; keep the box sealed and store flat in a cool, dry place to maintain tack.

At what point does the 28 lb paper weight limit how many sheets I can mail in one envelope?

The 28# sulphite stock handles typical multi-page catalogs or reports; total contents must stay within postal weight limits for the chosen service class.

Do these envelopes generate dust or static when run through a high-volume inserter all day?

The vellum finish on SFI-certified sulphite runs cleanly in automated inserters with minimal dust and low static buildup during continuous operation.
