Bsc Preferred M3348K Square Mailing Tubes 25 Pack

Product Description

The BSC PREFERRED M3348K is a square corrugated mailing tube designed for shipping rolled or cylindrical items without the handling problems associated with traditional round tubes. The square profile prevents rolling during packing and transit, keeping workstations and loading areas more organized. Each tube is a one-piece construction built from 200/ECT-32-B kraft corrugated board, which provides a reliable strength rating for standard parcel shipping. Tubes ship flat to minimize storage footprint and fold into shape quickly without tape or glue, reducing assembly time during high-volume pack-out operations. Sold in packs of 25.

These square mailing tubes are suited for shipping facilities, fulfillment centers, print shops, and any operation that regularly ships posters, blueprints, documents, or similar rolled goods. The flat-ship design makes them practical for stockrooms with limited shelf space. Their self-locking construction eliminates the need for additional adhesive supplies, keeping packaging workflows efficient. This product is appropriate for both light industrial and office shipping environments where consistent, repeatable packaging is required.

Installation Notes

No tools are required to assemble these tubes. Fold along pre-scored lines to form the square tube shape before inserting contents. Ensure the tube is fully closed and secured with appropriate packing tape before handing off to a carrier. Handle packed tubes carefully to avoid crushing the corrugated walls, which can compromise contents during transit.
