Partners Brand Self-Seal Flat Mailers

These kraft mailers measure 11 by 13 1/2 inches and arrive in a pack of 100. The self-sealing closure removes the need for tape or staples during packing. They suit offices, warehouses and home shippers who dispatch documents or flat goods regularly. The lightweight construction keeps postal costs down while protecting contents.

Sustained packing performance

The peel-and-seal adhesive stays tacky across high-volume mailing sessions without drying out. Each mailer seals firmly with hand pressure, so production lines maintain speed without equipment. The kraft material resists tearing when stuffed with catalogues, manuscripts or clothing. Repeated daily use does not degrade the seal reliability.

Build quality and daily handling

The 100-count box stores flat on shelves and dispenses one mailer at a time. Kraft fibre construction tolerates humidity better than coated alternatives, preventing curl in damp environments. The sealed flap creates a tamper-evident closure that shows obvious damage if opened. No reinforced edges or bubble lining are present, so sharp or heavy items need separate protection.

Questions about this item

Do the 11 x 13 1/2 inch mailers generate any noise, heat or power draw when stored all day?

No, these flat Kraft mailers are passive packaging supplies that produce no noise, heat or power consumption while sitting on a shelf.

What else must I already own for the self-seal closure on these 100 mailers to work?

Nothing extra is required; each mailer has a built-in adhesive strip that seals when pressed, so no tape, glue or dispenser is needed.

Can I use these 11 x 13 1/2 inch Kraft mailers with older label printers or handwritten addresses?

Yes, the plain Kraft surface accepts inkjet, laser or handwritten addressing without special equipment.
