The GLOBAL INDUSTRIAL B40313 is a corrugated tab lock literature mailer designed to protect flat documents, prints, and other paper materials during shipping and storage. Constructed from 200-B oyster white corrugated material, this mailer measures 12 inches long by 12 inches wide by 2 inches high and provides rigid side-wall protection against bending and crushing. Protective side flaps and a front outside tuck closure secure contents without tape, glue, or staples. Each unit ships and stores flat, making bulk inventory management straightforward for mailrooms, print shops, and distribution operations.
This mailer is suited for sending documents, blueprints, photographs, catalogs, and similarly flat materials that require protection from damage in transit. The tab lock design allows quick, tool-free assembly, making it practical in high-volume shipping environments. Sold in a pack of 50 units, it is a standard choice for offices, warehouses, and fulfillment centers that process regular document shipments.
Designed as a general-purpose flat literature mailer suitable for standard 12 inch by 12 inch documents, prints, and similarly dimensioned flat materials requiring rigid corrugated protection in transit.
No tools are required for assembly. Fold along pre-scored lines, engage the tab lock closure, and insert contents before sealing the front tuck flap. When storing flat stock, keep units in a dry environment to prevent moisture from weakening the corrugated walls. Check local carrier and postal regulations for any labeling or weight requirements before shipping.
