ECT (Edge Crush Test) measures the carton's stacking strength in pounds per inch². ECT-48 means your box can withstand up to 48 lbs of force per linear inch, making it suitable for heavy items, multi-level stacking, and extended transit times. This rating reduces product damage and minimizes chargebacks from damaged shipments.
Double wall ECT-48 boxes support approximately 65-75 lbs per individual carton under normal stacking conditions, with combined stack capacity exceeding 500 lbs when properly loaded on pallets. Actual capacity depends on contents weight distribution and environmental conditions (humidity, temperature).
Yes. ECT-48 double wall construction is designed for pallet stacking. A standard 48" x 40" pallet accommodates 20-24 assembled boxes per layer, enabling 3-4 layers safely (60+ boxes per pallet). This maximizes freight efficiency and reduces per-unit shipping costs significantly.
Flat boxes consume 80% less warehouse space during storage compared to pre-assembled cartons, lowering real estate costs and handling labor. Reduced storage volume also qualifies you for lower freight rates per bundle. Plus, bulk ordering in bundles of 10 improves unit economics and improves cash flow for high-volume shippers.
