The BSC PREFERRED MFL1292K is a kraft corrugated document mailer box sold in a pack of 50. Built from 200/ECT-32-B kraft corrugated material, this mailer is designed to protect flat documents, files, and important papers during shipping and storage. The design includes protective side flaps and a front outside tuck closure that locks the contents securely without requiring tape, glue, or staples. Each unit assembles in seconds, making it practical for high-volume mailing operations. The pack weighs 16.6 pounds and ships as a single unit of measure.
This mailer is suited for office environments, warehouses, print shops, and shipping departments that regularly send flat documents, contracts, blueprints, or legal files. The self-contained closure system eliminates the need for additional sealing supplies at the packing station. Each pack contains 50 individual mailer boxes, making it efficient for bulk document fulfillment operations. The ECT-32-B rating indicates the corrugated board meets standard edge crush test requirements for light-duty shipping applications.
Designed as an OEM-style equivalent to part number S-16935. Suitable for standard flat document mailing applications where a self-sealing corrugated mailer is required.
No tools required for assembly. Fold along pre-scored lines and tuck the front closure tab to secure the mailer. Store flat boxes in a dry location prior to use to maintain board integrity. No tape, glue, or staples are needed for standard closure.
