The BSC PREFERRED ML19122 is a white corrugated literature mailer box designed to ship flat documents, catalogs, brochures, and similar printed materials without the cost of a custom-sized carton. Built to 200/ECT-32-B corrugated board specification, the construction provides reliable crush resistance for standard freight and parcel handling. The box assembles in seconds with no tape, glue, or staples required, which reduces handling time during packing operations. Each pack contains 50 units, making it a practical stock item for mailrooms, print shops, warehouses, and distribution centers that process regular literature shipments.
This mailer is suited for residential and commercial shipping applications where a snug, secure fit for literature-sized pieces is needed without ordering custom packaging. The self-locking assembly design supports high-volume packing workflows. It is commonly used by fulfillment operations, print distributors, and office supply departments that require a consistent, ready-to-use literature shipping solution. The white corrugated exterior also accepts labels cleanly for routing and tracking purposes.
Designed as a direct equivalent replacement for part number S-3188. Suitable for shipping standard literature-sized printed materials including catalogs, brochures, and flat documents where a snug corrugated mailer fit is required.
No tools are required to assemble this mailer. Fold along pre-scored lines to form the box shape before inserting the literature piece. Ensure contents are positioned flat and centered before closing to maintain structural integrity during transit. Store flat in a dry environment to preserve board strength prior to use.
