Common questions
What does ECT-32 mean and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32 indicates the box can handle 32 lbf/in of force, suitable for single-wall applications in standard warehouse and parcel carrier handling. This rating ensures your products survive typical supply chain stresses without the cost premium of heavier-duty materials, optimizing your cost-per-unit while maintaining reliability.
How many of these boxes fit on a standard pallet, and what's the freight advantage?
The long, narrow profile stacks efficiently, typically 80 - 100 boxes per pallet depending on your assembly method. This narrow footprint reduces dimensional weight charges on parcel carriers and maximizes cube utilization in your warehouse, directly lowering per-box shipping costs.
Can ECT-32 boxes handle stacking weight in the warehouse?
Yes. ECT-32 single-wall corrugated is rated for typical warehouse stacking heights (4 - 5 boxes high) under standard conditions. For heavier items or taller stacks, consult our team for double-wall alternatives.
How quickly can I assemble and fill these boxes?
The long-side opening design accelerates packing compared to standard top-opening boxes, reducing assembly time and labor per unit. Boxes come flat for space-efficient storage and assemble in seconds by hand or with basic equipment.
