Common questions
What is ECT-32 and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32 indicates the box can withstand 32 pounds of pressure per linear inch when crushed along the edge. This rating ensures safe stacking in warehouses and during transit, preventing product damage while using single-wall construction to reduce packaging costs compared to double-wall alternatives.
How much weight can these 4x4x3 boxes safely hold?
ECT-32 single-wall boxes typically support 15-25 pounds per box depending on contents and stacking height. For exact payload specifications, consult our packaging engineers or test with your specific products to ensure optimal stack performance.
Are these boxes suitable for pallet stacking in high-volume warehouses?
Yes. ECT-32 kraft corrugated is engineered for standard warehouse pallet configurations and provides excellent stacking strength when loaded properly. The compact 3-inch height maximizes pallet utilization while maintaining structural integrity across 4-6 pallet heights.
Do you offer volume discounts or bulk pallet orders for these boxes?
Yes. We offer tiered pricing on bulk orders and full pallet quantities. Contact our B2B sales team for custom quotes on volume purchases, freight consolidation, and subscription pricing for ongoing fulfillment operations.
