The BSC PREFERRED MFL13133 is a white corrugated document mailer box built for secure, damage-free shipping of flat documents, certificates, contracts, and similar materials. Constructed from 200/ECT-32-B corrugated board, this mailer features protective side flaps and a front outside tuck closure that locks the contents in place without requiring tape, glue, or staples. The design allows fast assembly on a packing bench, reducing labor time during high-volume shipping operations. Each pack contains 50 units, making it practical for mailroom, warehouse, and office shipping stations handling regular document dispatch.
This mailer is suited for light commercial and office environments where flat, rigid document protection is required during transit. The self-locking tuck closure and corrugated side flap construction provide structural integrity for items that cannot be folded or rolled. Mailroom staff, shipping clerks, and warehouse personnel working in document-intensive operations will find this format efficient for repeated daily use. This product is equivalent to part number S-16948.
Designed as an OEM-style equivalent to part number S-16948. Suitable for standard document mailer applications in light commercial and office shipping environments.
No tools required for assembly. Fold side flaps into position and engage the front outside tuck closure to secure the mailer. Store flat in a dry location prior to use to maintain corrugated board integrity. Do not exceed the rated board strength by overpacking or applying excessive external compression during stacking.
