These 6 x 9 inch poly mailers are built from 2.5 mil polyethylene with a non-perforated lip and self-sealing adhesive strip, eliminating the need for tape or heat-sealing equipment at the packing station. The white exterior accepts labels, stamps, and direct ink printing, while the silver interior lining provides an additional barrier against scuffs and moisture exposure during transit.

Designed for lightweight, flat, and flexible goods, these mailers are a practical fit for e-commerce fulfillment centers, retail distribution, subscription box operations, and manufacturing outbound shipping. They handle clothing, documents, soft goods, and similar items reliably without adding unnecessary bulk or weight to outbound shipments.

Constructed with reinforced seam strength to hold up under overpacked conditions, the 2.5 mil wall resists puncture, tearing, and tampering throughout the shipping cycle. Each case contains 500 mailers, supporting cost-efficient bulk purchasing for facilities running continuous pick-and-pack workflows.
