Frequently Asked Questions

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.

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.
