Bsc Preferred M3312 Square Corrugated Mailer Tubes 25-pack

Product Description

The BSC PREFERRED M3312 is a pack of 25 flat-shipping, one-piece square corrugated mailer tubes designed for packing and sending rolled or tubular items through standard mail and parcel carriers. Unlike traditional round mailing tubes, the square profile prevents rolling during handling and on flat surfaces, making these tubes faster to load, stage, and ship. Constructed from 200/ECT-32-B white corrugated board, each tube assembles without tape or glue. They ship flat, reducing storage footprint on the shelf or in the stockroom until needed.

These square mailer tubes are suited for shipping facilities, warehouse pack stations, print shops, and any operation that regularly sends posters, blueprints, or similar documents. The flat-pack format means a single pack of 25 takes up minimal shelf space until assembly. The 200/ECT-32-B corrugated construction provides adequate crush resistance for standard parcel transit. Each unit assembles quickly, supporting high-volume pack-and-ship workflows without added materials or adhesives.

Installation Notes

No tools are required for assembly. Fold each tube along the pre-scored creases to form the square profile before inserting the item to be shipped. Ensure contents are secured inside before sealing the ends according to your facility's standard packing procedures. Store flat-packed tubes in a dry area away from moisture to maintain board integrity.
