These 12 x 4 x 3 inch white corrugated mailers are built from ECT-32-B single wall corrugated board and assemble into a finished box without tape, glue, or staples. The one-piece self-locking construction folds closed in seconds, eliminating consumables from the packing station and keeping throughput consistent under volume.
The folding structure creates double wall panels along the front and sides, adding crush resistance where transit pressure is highest. At approximately 0.23 lbs, they keep per-shipment weight low — an advantage for e-commerce operations, subscription box fulfillment, and light-product distribution where dimensional and actual weight both factor into carrier costs.
The white exterior is retail-presentable and accepts printed inserts or branded tissue without visual interference. Mailers are sold 50 per bundle and ship via parcel carrier, making them practical to reorder in quantities matched to fulfillment cycles rather than pallet-level commitments.
