The BSC PREFERRED M832 is a white corrugated mailer designed for shipping small, lightweight fragile items through standard mail and parcel services. Constructed from 200/ECT-32-B white corrugated board, each mailer folds to create double walls of protection on the front and sides without requiring tape, glue, or staples. The self-sealing fold-lock design reduces pack-out time and eliminates the need for additional fastening materials. This product ships and is sold in packs of 50. Warehouse staff, shipping clerks, and fulfillment teams are the primary users of this mailer format.
The M832 mailer is suited for e-commerce, retail fulfillment, and distribution center applications where lightweight fragile goods - such as photos, documents, small electronics, or collectibles - need crush-resistant protection during transit. The double-wall fold construction resists compression during stacking and handling. The white corrugated exterior also accepts labels and printing cleanly, making it practical for branded or unbranded shipments alike.
The M832 is an equivalent replacement for part number S-974. Suitable for general-purpose mailing and fulfillment applications requiring a self-locking corrugated mailer.
No tools are required for assembly. Fold the mailer along the scored lines to form the double-wall structure before inserting contents. Ensure the item fits within the interior dimensions without forcing the closure, as overfilling may compromise the lock tabs. Store flat in a dry environment to maintain board integrity prior to use.
