The BSC PREFERRED M20206 is a jumbo one-piece corrugated kraft mailer designed for shipping oversized flat items such as framed posters, artwork, and large documents. Built from 200/ECT-32-C kraft corrugated stock, this mailer offers a sturdy, economical solution for protecting large, flat shipments in transit. The single-piece design features pre-scored fold lines at multiple depth intervals, allowing the mailer to accommodate product depths from 1 to 6 inches without secondary packaging materials. Sold in a pack of 20 units, this item is suited for shipping departments, fulfillment operations, and packaging professionals handling high-volume or irregular flat goods.
This mailer is intended for residential and commercial shipping applications where standard box sizes fall short. It is particularly well-suited for framing shops, art studios, print-on-demand fulfillment centers, and retailers shipping large flat merchandise. The adjustable depth design reduces the need to stock multiple box sizes, simplifying packing workflows. This product is equivalent to part number S-14241, making it a direct cross-reference replacement for operations already sourcing that specification.
Designed as a direct equivalent to part number S-14241. Suitable for general shipping and fulfillment applications requiring a large-format, adjustable-depth corrugated mailer for flat or framed goods.
Place the product flat in the center of the open mailer. Fold the scored sides inward at the desired depth increment and secure all flaps with packing tape rated for the shipment weight. Do not exceed the 6-inch maximum depth score line, as doing so may compromise structural integrity. For heavy framed items, apply reinforcing tape along all seams before carrier handoff.
