38 x 26 x 6" Kraft Jumbo Mailers

These 38 x 26 x 6 inch jumbo easy-fold mailers are constructed from ECT-32-C single wall kraft corrugated board and built around an oversized flat mailer format rarely available through standard distribution. Multi-depth scoring (1", 2", 4", 6") lets assemblers adjust the finished box depth at pack-out, reducing the number of distinct mailer sizes a facility needs to maintain on the shelf.

The large footprint makes these mailers well suited for retail apparel, framed artwork, architectural drawings, large print media, and bulky flat goods moving through e-commerce or wholesale distribution channels. The easy-fold design requires no specialized tooling or assembly equipment, supporting consistent pack-out speed on high-volume lines.

Each mailer weighs approximately 2.24 lbs and is sold in bundles of 20. At this size, freight delivery is required — factor carrier scheduling into replenishment lead times accordingly.
