The #4 Jiffy® Utility Self-Seal Paper Mailer is a natural brown kraft paper mailer built to resist bending, creasing, and folding in transit. Its double-fold, double-glued bottom flap reinforces the most stress-prone point of the mailer, while a self-seal peel-and-stick strip and integrated tear strip deliver tape-free closure at the packing station and clean opening on the receiving end.

These mailers are well-suited for e-commerce fulfillment, retail distribution, direct mail, and publishing operations. They accommodate flat documents, soft goods, apparel, and similarly dimensioned printed materials without requiring additional protective packaging in most light-duty shipping scenarios.

Kraft construction is 100% recyclable, supporting sustainability programs without sacrificing durability. Each case contains 250 mailers and ships via parcel carrier.
