These 10 x 13 inch polyethylene mailers deliver reliable, lightweight envelope protection at 2.5 mil thickness. The poly construction resists tearing, puncturing, and moisture exposure throughout the shipping cycle, while high-strength seams maintain integrity even when contents are packed to capacity.

The self-seal adhesive strip eliminates tape and heat-sealing equipment from the packing line, accelerating throughput in e-commerce fulfillment centers, retail distribution operations, and direct mail environments. Apparel, soft goods, documents, and flat media all ship securely within the interior opening.

The white exterior accepts labels, stamps, and direct ink printing without adhesion issues. A silver inner lining adds opacity for shipment security. Each case contains 1,000 mailers and ships via parcel carrier.
