Common questions
Why choose square tubes over round mailing tubes?
Square tubes prevent rolling during transit, pack more efficiently into shipping boxes, and are easier for warehouse staff to handle and organize. This reduces damage claims and packing time while maximizing pallet space, lowering your cost per unit shipped.
Do these tubes require tape or glue to assemble?
No. These one-piece tubes fold together quickly by hand without tape, glue, or additional fasteners, simplifying your packing process and eliminating supply chain delays.
What does ECT-32-B corrugated mean?
ECT-32-B indicates an Edge Crush Test rating of 32 pounds per inch (minimum), meaning these tubes can withstand significant stacking pressure. This ensures your products arrive damage-free even in demanding shipping environments.
Are these tubes shipping-compliant for major carriers?
Yes. ECT-32-B white corrugated construction meets FedEx, UPS, and USPS shipping standards for corrugated packaging, ensuring your shipments clear carrier inspections and qualify for standard rates without surcharges.
