Bsc Preferred M3318K Square Corrugated Mailing Tubes 25pk

Product Description

The BSC PREFERRED M3318K is a pack of 25 flat-shipping square corrugated mailing tubes designed for packaging and shipping applications. Unlike traditional round mailing tubes, the square profile prevents rolling during handling and staging, making them easier to pack, sort, and ship. Each tube is constructed from 200/ECT-32-B kraft corrugated material, providing reliable crush resistance for standard mailing loads. The one-piece design folds together quickly without tape or glue, reducing assembly time at the packing station. Each pack contains 25 tubes and ships flat to minimize storage footprint in warehouse and distribution environments.

These square mailing tubes are suited for shipping facilities, fulfillment centers, print shops, and any operation that regularly ships rolled or elongated documents, posters, blueprints, or similar materials. The flat-pack format makes them practical for high-volume operations where storage space is at a premium. The no-adhesive, fold-together construction allows packing staff to assemble tubes on demand without additional supplies. Sold in packs of 25, the M3318K is appropriate for both steady-volume shippers and occasional-use applications.
