These 5 x 5 x 37 inch kraft square mailing tubes are built from ECT-32-B single-wall corrugated board, giving them a rigid, flat-sided profile that eliminates rolling during transit and handling — a practical advantage over round tubes on conveyor systems, packing benches, and storage shelving.
The square format makes these tubes a reliable choice for posters, blueprints, architectural drawings, banners, fabric rolls, and other elongated items that require a stable, crush-resistant enclosure. Print shops, architectural firms, trade show suppliers, and apparel distributors commonly use this tube format to protect high-value rolled goods through the shipping process.
Each tube is manufactured as a single piece that ships flat and folds together without tape or glue, reducing both storage footprint and assembly time. At 0.73 lbs per unit, the lightweight construction helps manage dimensional weight costs. Tubes are sold in bundles of 25 and ship via parcel carrier.
