Common questions
What is ECT-32 and why does it matter for my shipping costs?
ECT (Edge Crush Test) -32 measures corrugated strength and stacking capacity. ECT-32 handles typical B2B warehouse conditions and supports multi-box stacking on pallets, reducing the number of shipments needed and lowering total freight spend.
Can I use 4x4x16 boxes on standard 40x48" pallets?
Yes. The compact 4x4" footprint allows 10 boxes per layer (in a 2x5 arrangement) on a standard pallet, maximizing density and freight efficiency for cost-conscious volume shippers.
Is this a good alternative to mailing tubes for long items?
Absolutely. Corrugated boxes offer protection, easier labeling, and lower dimensional weight charges than tubes. The rigid construction prevents crushing during transit and stacking.
How many boxes do I need per pallet for optimal shipping economics?
A full pallet can safely hold 250 - 300 boxes (10 - 12 layers of 25-box stacks), achieving excellent per-unit economies on LTL or truckload shipments. Our team can help calculate your volume needs.
