Common questions

Why choose square tubes instead of round mailing tubes?
Square tubes prevent rolling during packing and transit, reducing product movement, crushing, and labor time spent securing items. They also stack efficiently on shelves and in vehicles, maximizing space utilization and reducing shipping dimensional weight fees.
How long does assembly take per tube?
Each tube folds and locks in seconds without requiring tape, glue, or tools. Your team can assemble 100+ tubes per hour, significantly accelerating fulfillment operations compared to glued or taped alternatives.
What is ECT-32-B corrugated material?
ECT-32-B (32 ECT = Edge Crush Test) is a medium-duty white corrugated material that provides excellent puncture resistance and compression strength. It meets ISTA and ASTM shipping standards, ensuring compliance with carrier requirements for protected shipments.
Are these tubes compatible with major shipping carriers?
Yes. ECT-32-B construction meets FedEx, UPS, USPS, and DHL dimensional and material requirements. The sturdy corrugated design protects contents through multi-carrier transit while minimizing dimensional weight surcharges due to the compact flat-ship format.
