8 1/2 x 14 1/2" #3 Jiffy® Utility Self-Seal Paper Mailers

The #3 Jiffy® Utility Self-Seal Paper Mailer is a natural brown kraft paper mailer measuring 8 1/2 x 14 1/2 inches, built with a double-fold, double-glued bottom flap that reinforces corners and edges without tape or additional closure materials. The peel-and-strip self-seal adhesive strip closes the mailer securely in one motion, eliminating the need for tape at the packing station.

These mailers are well-suited for e-commerce fulfillment, retail distribution, direct mail, and document shipping. The slim, flat profile reduces storage footprint and lowers dimensional weight relative to padded or rigid alternatives, making them a practical choice for flat goods, flexible items, printed materials, and lightweight products that need a clean, secure enclosure.

Natural kraft construction is 100% recyclable. Each case contains 250 mailers and ships via parcel carrier, accommodating both routine replenishment and larger inventory builds.
