Common questions
Why choose ECT-44 over standard ECT-32 corrugated?
ECT-44 delivers 40% greater stacking strength and edge crush resistance, enabling multi-tier storage without box failure or product damage. For high-volume warehousing, this reduces damage claims by 25-35% and allows taller pallet stacks, improving cubic utilization by up to 20%.
How many 6x6x6 boxes fit on a standard pallet?
A single pallet can accommodate 40-50 bundles (1,000-1,250 flat boxes), depending on stacking height and your warehouse layout. When assembled, expect 30-40 boxes per layer with optimal vertical stacking for maximum storage density.
Is this box suitable for heavy items?
Yes. ECT-44 single-wall corrugated safely handles items up to 15-20 lbs per carton when stacked 3-4 high. For heavier products, consider double-wall alternatives or limiting stack height to 2 cartons to maintain structural integrity.
What is the minimum order quantity?
Minimum order is 1 bundle of 25 cartons. Volume discounts apply at 10+ bundles (250+ boxes), with additional pricing breaks at 50+ bundles and pallet quantities (1,000+ boxes).
