Common questions
What does ECT-44 mean and why does it matter?
ECT (Edge Crush Test) rating of 44 indicates the corrugated material can withstand 44 pounds of pressure per linear inch. This heavy-duty rating ensures your boxes won't collapse under stacked weight in warehouses or during multi-stop delivery routes, directly reducing product loss and customer complaints.
How many boxes can I stack safely with 20x20x20 dimensions?
With ECT-44 single-wall construction, you can safely stack 5-7 boxes high when fully loaded (depending on item weight), maximizing vertical storage in standard 8-10 foot warehouse clearances while maintaining structural integrity and meeting ISTA shipping standards.
Are these boxes suitable for fragile or delicate items?
Yes. The 40% strength advantage over standard cartons, combined with ECT-44 rated walls, provides exceptional protection for fragile goods. Pair with appropriate void fill and cushioning materials for optimal protection during transit.
What's the volume discount potential with bulk ordering?
Ordering in larger bundle quantities (100+ boxes) delivers significant per-unit savings and reduces administrative overhead. Contact our B2B team for custom volume pricing, tiered discounts, and freight consolidation options tailored to your fulfillment volume.
