The BSC PREFERRED MFL1183 is a white corrugated document mailer box sold in a pack of 50. Constructed from 200/ECT-32-B single-wall corrugated board, it provides rigid protection for flat documents, certificates, contracts, and other materials that cannot be folded or bent. The design features protective side flaps and a front outside tuck closure that locks the contents securely without requiring tape, glue, or staples. The self-assembly construction allows each mailer to be set up in seconds, reducing packing time in high-volume shipping environments. This product is equivalent to part number S-11227.
Intended for office supply rooms, mailrooms, shipping departments, and fulfillment operations that regularly send critical documents. The white corrugated surface accepts labels cleanly and presents a professional appearance. Sold as a pack of 50 units, this mailer is suited to businesses that ship documents in recurring volume and need a consistent, damage-resistant solution. The tuck-closure design eliminates the need for secondary sealing materials on the exterior.
Designed as a drop-in equivalent to part number S-11227. Suitable for standard document mailer applications requiring a self-sealing corrugated mailer with side-flap protection.
Fold along pre-scored lines to assemble the mailer box before inserting documents. Confirm the tuck closure is fully seated before placing in outbound shipment. No additional sealing materials are required, though additional tape may be applied at the discretion of the shipper for high-value contents.
