The BSC PREFERRED M22186 is a jumbo one-piece corrugated kraft mailer designed for shipping oversized flat items such as framed posters and artwork. Built from 200/ECT-32-C kraft corrugated material, it provides sturdy protection during transit without requiring a separate outer box. The mailer features pre-scored fold lines at multiple depths, allowing the user to adjust the box depth anywhere from 1 to 6 inches to match the actual thickness of the contents. Each pack contains 20 mailers. This format is commonly used in fulfillment operations, print shops, and art supply retailers that ship large-format items regularly.
This mailer is suited for residential and commercial shipping applications where standard-size boxes fall short. It is particularly useful for framed artwork, posters, canvas prints, and similarly shaped flat or shallow items that require a snug, custom-depth fit. The single-piece construction eliminates the need for a separate lid or bottom piece, reducing assembly time on the packing bench. Sold in packs of 20, this SKU is appropriate for moderate-volume shipping operations as well as occasional high-volume runs.
This product is equivalent to part number S-14242. Designed as a general-purpose jumbo corrugated mailer suitable for standard shipping and fulfillment applications requiring variable-depth flat packaging.
No tools are required for assembly. Place the item face-down in the center of the mailer, fold in the side panels at the desired depth score line, and secure all seams with pressure-sensitive or reinforced packing tape. For heavier framed items, apply tape along all outer seams to prevent opening in transit. Ensure the chosen depth setting allows the contents to sit flush before sealing.
