Common questions
What does ECT-48 mean and why does it matter?
ECT (Edge Crush Test) measures the vertical stacking strength of corrugated material. ECT-48 means this box withstands 48 lbs of force per linear inch, supporting heavy loads across multiple tiers, critical for high-density warehouses where boxes stack 6-8 pallets high.
How much can I stack these boxes safely?
With proper load distribution, ECT-48 double wall boxes support 5-6 layers of loaded boxes (50-60 lbs each) before structural degradation. Actual stacking height depends on product weight and warehouse conditions; consult our stacking guide for your specific payload.
Will flat-shipping reduce my packaging costs?
Yes. Flat-shipped boxes reduce inbound freight volume by ~75% versus pre-assembled competitors, lowering LTL costs per shipment. Over annual volume, this translates to $2,000-$5,000 savings for mid-size fulfillment operations.
Can I use these for food products or hazmat?
These kraft double wall boxes are food-safe and FDA-compliant for dry goods, bakery, and prepared foods. For hazmat, consult our compliance team, ECT-48 may meet IATA standards depending on product classification and weight.
