Common questions
Why choose square tubes over traditional round mailing tubes?
Square tubes eliminate rolling during packing and shipping, reducing product damage and packing time. They also stack efficiently in boxes and on shelves, maximize carton space utilization, and provide stability on conveyor systems, lowering your total cost of operation.
What products can I safely ship in 3 x 3 x 25" tubes?
These tubes are engineered for rolled documents, blueprints, posters, textiles, rolled plastics, foam tubes, and cylindrical parts up to 25 inches. The ECT-32-B corrugated material provides adequate protection for most light-to-medium-weight items in standard ground and parcel shipping.
How quickly can my team assemble these tubes?
Each tube folds together in seconds without tape, glue, or fasteners. Trained operators can assemble 100+ tubes per hour, making these ideal for high-volume fulfillment centers and production environments where labor efficiency directly impacts margins.
Are these tubes compliant with major shipping carrier requirements?
Yes. The ECT-32-B construction meets standard corrugated specifications for UPS, FedEx, and USPS. The rigid square design provides proper edge crush performance and ensures your shipments meet carrier stacking and handling guidelines without additional reinforcement.
