Common questions
What does ECT-32 mean and why does it matter?
ECT (Edge Crush Test) 32 means this single-wall corrugated board withstands 32 lbs of force per linear inch before crushing. For mid-weight items, ECT-32 balances protection and cost, ideal for most fulfillment applications without over-specification.
How much weight can these boxes safely stack?
ECT-32 single-wall boxes typically support 3 - 5 boxes stacked when properly loaded. Actual stacking performance depends on product weight and load distribution; consult our stacking charts or contact support for your specific use case.
Will these boxes reduce my freight costs?
Yes. The narrow 4 x 4" footprint maximizes pallet density, reducing dimensional weight charges. Compared to oversized boxes for long items, you'll ship more units per pallet and lower your per-unit freight expense.
Can I order custom printing or sizes?
Standard kraft boxes ship off-the-shelf for fast turnaround. For custom printing, graphics, or non-standard dimensions, contact our B2B sales team for volume quotes and lead times.
