The BSC PREFERRED MFL17112 is a white corrugated document mailer box designed for secure, protective shipment of flat documents, folders, and similar materials. Constructed from 200/ECT-32-B single-wall corrugated board, each mailer features protective side flaps and a front outside tuck closure that locks contents in place without tape, glue, or staples. The self-assembly design allows a technician, warehouse worker, or shipping clerk to set up each box in seconds. Sold in a pack of 50 units, this product suits high-volume mailing and fulfillment operations where consistent, reliable packaging is required.
These mailer boxes are suited for office environments, distribution centers, and shipping departments that regularly send critical documents, contracts, blueprints, or flat media. The self-locking tuck closure eliminates the need for additional sealing materials, reducing prep time per shipment. The white corrugated finish provides a clean appearance appropriate for professional correspondence or outbound customer shipments. Each unit in the pack offers the same structural integrity, making bulk use straightforward and consistent.
Designed as a standard corrugated document mailer for general flat-document packaging and shipping applications across office, warehouse, and fulfillment environments.
No tools or adhesives are required to assemble these mailer boxes. Fold along the pre-scored lines and engage the tuck closure before inserting contents. Store flat in a dry location to maintain board integrity prior to use. Handle with care to avoid crushing or moisture exposure that could compromise the ECT-32-B corrugated structure.
