Common questions
Why choose square tubes over traditional round mailing tubes?
Square tubes eliminate rolling during transport, reducing product damage and packing labor. The non-rolling design means faster warehouse operations, better stackability on pallets, and reduced need for void fill materials. They also pack more efficiently into shipping containers compared to round alternatives.
How quickly can employees assemble these tubes?
Each tube folds together in seconds without tape, glue, or tools. The pre-scored design allows trained staff to assemble 200-300 tubes per hour, significantly reducing packing labor costs compared to two-piece tubes or traditional assembly methods.
What compression strength does ECT-32-B corrugated provide?
ECT-32-B (Edge Crush Test 32 pounds per linear inch) provides 2,200+ PSI compression strength, supporting full pallet stacking and withstanding standard industrial shipping conditions for heavy rolled documents and premium products.
Are these tubes compliant with shipping carrier specifications?
Yes. White square tubes meet FedEx, UPS, and USPS dimensional weight requirements. The 4" x 4" x 25" configuration optimizes dimensional weight billing across all major carriers, reducing per-unit shipping costs by 15-25% compared to oversized packaging.
