A strong self-sealing adhesive strip ensures fast, efficient packing—just insert the item, peel, and press to securely seal your shipment. The tamper-resistant closure provides peace of mind, preventing contents from being replaced or exposed during transit. Each bag also accepts adhesive labels or permanent marker addressing for smooth fulfillment.

Our poly mailers are waterproof, tear-resistant, and carrier-approved, featuring reinforced seams and generous flaps for easy over-stuffing. Whether you're mailing shirts, sweaters, jeans, books, accessories, or boutique gifts, your items stay clean, dry, and protected from warehouse to doorstep.
