40 x 30 x 6" Kraft Jumbo Mailers

These 40 x 30 x 6 inch jumbo kraft easy-fold mailers are built from ECT-32-C single wall corrugated board and feature a fold-flat design that requires no assembly equipment. Multi-depth scoring (1", 2", 4", 6") allows the box depth to be reduced in increments, letting packers match container height to load height — minimizing void fill and keeping contents stable during transit.

The large footprint handles oversized flat goods that exceed standard mailer dimensions: large printed materials, foam-backed components, architectural drawings, bulky apparel, and unframed canvas or textile panels are all natural fits. Manufacturers, fulfillment centers, and print distributors shipping high-volume large-format product lines benefit most from this format.

Each mailer weighs approximately 2.48 lbs. Sold in bundles of 20. Due to their size and weight, these mailers require freight delivery — parcel shipment is not available for this item.
