These 10 x 5 x 5 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and assemble using a one-piece fold design that requires no tape, glue, or staples. The interlocking construction reduces pack-out time and eliminates the need for additional sealing supplies at the packing station.

The folded structure creates double walls on the front and sides, adding transit rigidity suited for e-commerce fulfillment, warehouse distribution, retail replenishment, and direct-to-consumer parcel shipping. At 0.33 lbs, these mailers keep shipment weight low — a practical advantage for postage-sensitive operations.

Mailers store and ship flat for high-density storage efficiency. The natural kraft finish carries no additional coating or color treatment. Sold in bundles of 50 and parcel-friendly for standard carrier accounts.
