The BSC PREFERRED ML961 is a white corrugated literature mailer box designed to ship flat documents, catalogs, and printed materials without the cost of a custom carton. Built to 200/ECT-32-B corrugated board standards, it delivers reliable crush resistance for standard mailer applications. The box assembles in seconds with no tape, glue, or staples required, making it well suited for high-volume shipping operations, mailrooms, and supply rooms where speed and consistency matter. The package includes 50 mailer boxes per pack.
This mailer is used in commercial and light industrial settings where literature, brochures, manuals, or flat printed materials need secure, damage-resistant packaging. It fits standard document and catalog sizes without modification. The no-fastener assembly design reduces labor time during pack-out and is appropriate for distribution centers, office supply operations, and trade contractor offices managing regular outbound mailings.
The ML961 is equivalent to part number S-9849. Designed as a standard replacement or equivalent for white corrugated literature mailers in that size class.
No tools are required to assemble this mailer box. Fold along pre-scored lines in the correct sequence to avoid misalignment before loading contents. Store flat in a dry location to preserve board integrity and ease of assembly. Handle stacked inventory carefully to prevent edge crushing prior to use.
