These 4 x 4 x 37 inch white square mailing tubes are built from ECT-32-B white corrugated board, delivering a rigid, crush-resistant structure designed to protect posters, banners, blueprints, fabric rolls, and other elongated items through the full shipping cycle.
The square cross-section is a practical advantage over round tubes: it eliminates rolling on packing benches and conveyor lines, keeping tubes stationary during pack-out. Fulfillment centers, print shops, architectural firms, and fabric distributors all benefit from the added handling control this profile provides.
Each tube is a one-piece design that arrives flat for compact storage and folds together without tape or glue, reducing assembly time at high-volume stations. At approximately 0.606 lbs per unit, these tubes are lightweight relative to their 37" length. Each bundle contains 50 tubes.
