Common questions
How does ECT-44 compare to standard ECT-32 boxes for stacking strength?
ECT-44 delivers 40% greater stacking strength than ECT-32, enabling safer multi-level palletization and reducing freight damage. For high-velocity operations, ECT-44 reduces claim rates and improves supply chain ROI through edge crush resistance and burst performance.
What's the maximum pallet stack height with these 18 x 12 x 12" boxes?
Stack height depends on product weight and environmental conditions, but ECT-44 construction typically supports 6-8 boxes high on standard pallets. Consult our stacking calculator or contact our logistics team for your specific product weight and warehouse conditions.
Are these boxes suitable for fragile items or electronics?
Yes. The ECT-44 kraft corrugated provides excellent cushioning and impact protection. For delicate electronics, combine with appropriate internal packaging materials (foam, air pillows, or kraft paper) to exceed fragile goods shipping standards.
How many boxes per pallet, and what's the freight savings vs. standard boxes?
Approximately 200-250 flat boxes per pallet (depends on bundling). The 18 x 12 x 12" footprint optimizes standard pallet dimensions, reducing dimensional weight charges by 8-12% compared to oversized alternatives while maintaining durability and lower total cost per unit shipped.
