The BSC PREFERRED M28226 is a jumbo one-piece kraft corrugated mailer designed for shipping oversized flat items such as framed posters, artwork, and similarly sized products that standard mailers cannot accommodate. Built from 200/ECT-32-C corrugated kraft board, this mailer provides rigid protection during transit without requiring additional packaging materials. Scored at multiple depths, the mailer adjusts to fit products ranging from 1 to 6 inches in depth. Warehouse staff, fulfillment operations, and shipping departments install and close these mailers by folding the side panels to the desired depth score and securing with tape. Sold in a pack of 20 units.
The M28226 is suited for e-commerce fulfillment, art galleries, print shops, and any shipping operation that regularly handles large, flat, or framed items. The multi-depth scoring eliminates the need to stock multiple box sizes for varying product thicknesses, reducing storage requirements and material waste. The single-piece design speeds up pack time compared to multi-piece alternatives. At a package weight of approximately 27.18 pounds per pack of 20, these mailers are substantial enough for demanding shipping environments while remaining manageable on a packing bench.
Designed as an OEM-style equivalent to part number S-9857. Suitable for general-purpose oversized flat-item shipping across fulfillment, print, and art-distribution applications.
Place the product face-down in the center of the mailer on the appropriate depth score line. Fold the side panels inward at the desired depth and secure all seams with pressure-sensitive or water-activated tape rated for corrugated cartons. No tools are required for assembly. Ensure the tape seal covers all flap edges to prevent shifting or moisture intrusion during transit.
