These jumbo fold-over mailers are built from ECT-32-B white corrugated board, delivering rigid flat protection across a large 30 x 22 1/2 inch footprint. The fold-over flap design requires no separate lid — load contents, fold the flaps inward, and tape to close, reducing assembly time at the packing station.

The white exterior and clean finish make these mailers a practical choice for e-commerce fulfillment, retail distribution, and direct-to-consumer shipments where appearance supports brand presentation. Print distributors, poster and calendar shippers, and manufacturers sending large flat components rely on this format to keep oversized contents protected and flat through transit.

Constructed to ECT-32-B single wall B-flute spec, these mailers balance rigidity with a weight-conscious footprint — approximately 1.14 lbs — helping manage carrier costs on large flat shipments. Sold in bundles of 20 and ships via parcel carrier.
