Bsc Preferred M5548K Square Corrugated Mailing Tubes 25pk

Product Description

The BSC PREFERRED M5548K is a pack of 25 square corrugated mailing tubes constructed from 200/ECT-32-B kraft corrugated material. Unlike traditional round mailing tubes, the square profile prevents rolling during handling and storage, making these tubes easier to pack, stack, and ship. Each tube ships flat to maximize storage efficiency in a warehouse or mail room, then folds together quickly without tape or glue. These tubes are sold as a pack of 25 and are suited for shipping and distribution facilities that need a reliable, no-assembly-required mailer format.

These square mailing tubes are intended for packaging and shipping operations where standard round tubes create handling or space challenges. Their flat-ship, self-locking design speeds up fulfillment lines and reduces the footprint of unassembled packaging stock. The 200/ECT-32-B corrugated construction provides adequate crush resistance for typical mailing and parcel applications. This product fits into mailer and corrugated packaging categories used by distribution centers, print shops, poster and document mailers, and general fulfillment operations.

Installation Notes
