Square tubes eliminate rolling during transit, preventing product damage and shifting inside the package. They also pack more efficiently on pallets, reducing shipping costs and improving warehouse utilization compared to round designs.
Assembly is tool-free and tape-free. Each tube folds together in seconds without glue or fasteners, allowing your team to prep dozens of shipments per hour.
These tubes accommodate rolled documents, blueprints, posters, fishing rods, telescopes, pvc pipe, promotional materials, artwork, and any item up to 48 inches in length with a maximum cross-section of 5x5 inches.
The ECT-32-B corrugated material provides solid crush resistance for standard shipments. For fragile items, we recommend adding interior padding. Verify hazmat regulations with your carrier before shipping regulated materials.
