These 12 x 5 x 4 inch white corrugated mailers are built from ECT-32-B single wall board and assembled using a one-piece fold-lock design that requires no tape, glue, or staples. The structure closes securely in seconds, making it practical for high-volume packing lines where speed and consistency are priorities.
The folded construction creates double wall panels along the front and sides, adding compression resistance during transit. The white exterior accepts direct printing, shipping labels, and branded overlays cleanly, making these mailers a natural fit for e-commerce fulfillment, retail distribution, subscription box operations, and direct-to-consumer outbound shipping.
Each mailer weighs approximately 0.33 lbs. Sold in bundles of 50 and ships via parcel carrier.
