Product Description

The BSC PREFERRED MFL444K is a kraft corrugated mailer box designed to protect documents and flat materials during shipping and storage. Built from 200/ECT-32-B kraft corrugated board, this mailer delivers reliable crush resistance for sensitive contents. The design features protective side flaps and a front outside tuck closure that locks the box shut without tape, glue, or staples. Each unit assembles in seconds, making it practical for high-volume shipping operations. Sold in packs of 50, this mailer suits mailrooms, fulfillment centers, and distribution operations where consistent packaging throughput matters.

This mailer box is suited for shipping and storing documents, flat media, and other items requiring secure, rigid enclosure. The tuck-front closure and side flaps provide full coverage on all panels, reducing the risk of contents shifting or being exposed in transit.

Packaging and shipping professionals working in fulfillment, office supply, or records management settings will find this format practical for everyday outbound document mailers.
