The BSC PREFERRED MFL1182K is a kraft corrugated document mailer box designed to protect flat documents, certificates, prints, and similar materials during shipping and storage. Built from 200/ECT-32-B kraft corrugated board, this mailer features protective side flaps and a front outside tuck closure that locks contents securely without requiring tape, glue, or staples. The self-assembly design allows technicians, warehouse staff, and shipping departments to set up each mailer in seconds. Sold as a pack of 50 units, this product is a direct equivalent to part number S-16951.
This mailer is suited for office supply rooms, distribution centers, print shops, and any operation that regularly ships flat or rigid documents requiring maximum edge and surface protection. The corrugated construction provides rigidity that protects contents against bending and crushing during transit. The front tuck closure keeps the mailer sealed without additional sealing materials, streamlining pack-out operations.
Equivalent to part number S-16951. Designed as a standard corrugated document mailer suitable for flat document shipping applications across commercial and industrial packing operations.
No tools are required to assemble this mailer. Fold along pre-scored lines to form the box, insert documents, tuck the front closure flap to seal, and apply any required shipping labels to the exterior surface. Do not overfill beyond the intended document capacity, as overloading may compromise the tuck closure and reduce edge protection.
