These 19 x 24 inch white poly mailers are built from 2.5 mil polyethylene with a self-seal pressure-sensitive closure that eliminates the need for additional tape. The white exterior accepts shipping labels, stamps, and ink without surface prep, while a silver interior lining adds a secondary layer of protection for contents.

The format handles apparel, soft goods, folded textiles, documents, and flexible packaged goods. High-strength seams maintain integrity under full and overpacked loads, making these mailers dependable for e-commerce fulfillment, subscription box operations, retail distribution, and wholesale order shipping.

Constructed from puncture and tear-resistant polyethylene with moisture-barrier properties, each mailer is ready to seal without tools or additional materials. Cases contain 125 mailers and ship via parcel carrier. Order single cases or multiples to match your ongoing fulfillment volume.
