These 10 x 4 x 4 inch kraft corrugated mailers are built from ECT-32-B board and close without tape, glue, or staples. The one-piece blank folds into a double-walled structure along the front and sides, securing contents through the folding mechanism alone — no additional materials required at the packing station.
The self-locking design suits e-commerce fulfillment operations, retail distribution centers, and light manufacturing environments where packing speed and material efficiency matter. Each mailer ships and stores flat, reducing staging space on the line and in storage.
At approximately 0.24 lbs, the mailers keep per-shipment weight low across high-volume runs. Sold in bundles of 50 and parcel-friendly, making restocking practical for facilities running continuous outbound volume.
