Partners Brand Self-Seal Flat Mailers 11 x 13 1/2 Kraft PK100

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.
