Common questions
What does ECT-48 rating mean and why does it matter?
ECT (Edge Crush Test) measures how many pounds per lineal inch a box edge can withstand. ECT-48 means each carton edge supports 48 lbs/inch, ideal for stacking multiple boxes high without collapse, critical for warehouse efficiency and damage prevention.
How much weight can these double wall boxes handle?
ECT-48 double wall cartons typically support 40-65 lbs per box depending on contents, with stacking capacity of 3-4 boxes high under typical warehouse conditions. Exact crush strength depends on product weight distribution and pallet configuration.
Will flat-shipped boxes reduce my storage costs?
Yes. Flat cartons consume 80-90% less warehouse space than pre-assembled boxes and reduce inbound freight weight by up to 50%, directly lowering per-unit packaging costs for high-volume operations.
Are these boxes certified for hazardous or regulated shipments?
These ECT-48 kraft cartons meet standard corrugated shipping specifications. For DOT hazmat, pharmaceutical, or international compliance, confirm specific regulations apply. Contact our team for certified variant options.
