The BSC PREFERRED M1266 is a corrugated mailer designed for shipping small, lightweight, and fragile items through standard mail and parcel carriers. Manufactured from 200/ECT-32-B white corrugated board, these mailers fold to create double walls on the front and sides, providing crush resistance during transit. The self-locking design requires no tape, glue, or staples, reducing pack-out time at the shipping station. Each pack contains 50 mailers. Shipping and warehouse operations staff rely on these for consistent, repeatable protection without additional sealing supplies.
These mailers are suited for light-duty parcel shipping in retail fulfillment, e-commerce, and warehouse distribution environments. Their lightweight construction helps control postage costs on small-item shipments. The white corrugated surface accepts labeling and marking clearly, making them appropriate for professional outbound shipments. The fold-and-lock closure keeps contents secure without added materials, streamlining high-volume pack-out workflows.
Designed as a direct equivalent to part number S-9856. Suitable for shipping small, lightweight fragile items through standard parcel and mail carriers.
No tools or adhesives are required to assemble these mailers. Follow the fold lines to form the double-wall structure before placing contents inside. Ensure items are properly cushioned or wrapped before insertion for maximum protection during transit. Verify item dimensions against mailer interior dimensions prior to committing to high-volume use.
