Bsc Preferred M5525K Square Corrugated Mailing Tubes 25pk

Product Description

The BSC PREFERRED M5525K is a pack of 25 square kraft corrugated mailing tubes designed for packing and shipping documents, prints, and rolled goods. Unlike round mailing tubes, the square profile prevents rolling during storage and transit, making them easier to pack and stack. Each tube is a one-piece construction built from 200/ECT-32-B kraft corrugated board. They ship flat to conserve shelf and storage space, then fold together quickly without tape or glue. This pack is sold as a unit of 25 tubes and is equivalent to part number S-1575K.

These square mailing tubes are suited for shipping and fulfillment operations that regularly send documents, blueprints, posters, or similar rolled items. The flat-fold design reduces storage footprint in warehouse and mailroom environments. The square cross-section improves stackability on shelves and in shipping containers compared to standard round tube mailers. Suitable for light commercial and high-volume shipping applications where consistent, reliable tube mailers are needed in quantity.
