The BSC PREFERRED MFL18124K is a corrugated document mailer box sold in a pack of 25. It is designed to protect flat documents, files, and records during shipping and storage. The box is manufactured from 200/ECT-32-B kraft corrugated material, which provides rigid wall strength suitable for standard parcel shipping. Protective side flaps and a front outside tuck closure hold contents securely without requiring tape, glue, or staples. This mailer is typically handled by shipping, mailroom, and warehouse staff in office, industrial, and supply chain environments.
This mailer is suited for shipping important documents, contracts, blueprints, and flat media that require edge and surface protection in transit. The self-locking tuck closure design allows fast assembly on high-volume packing lines or lower-volume mailroom operations. The 200/ECT-32-B corrugated construction meets standard single-wall box strength requirements, making it appropriate for ground and air parcel shipments. Each pack contains 25 units, supporting both bulk and moderate-volume mailing needs.
Designed as a direct equivalent to part number S-16963. Suitable for standard flat-document mailing and shipping applications across office, warehouse, and fulfillment environments.
No tools are required for assembly. Fold along scored lines and engage the tuck closure before inserting documents. Ensure contents are fully seated before closing to prevent shifting in transit. Store flat in a dry location to maintain corrugated wall integrity prior to use.
