Common questions
What does ECT-48 mean and why does it matter for my shipments?
ECT (Edge Crush Test) 48 indicates the carton can withstand 48 pounds of force per linear inch before crushing. For B2B operations, this high rating ensures your products remain protected through stacking in warehouses and during multi-stop freight routes, reducing damage claims and returns.
How much weight can these double wall boxes safely hold?
ECT-48 double wall boxes safely hold 65+ lbs per box depending on contents and stacking height. They're engineered for 4-6 high stacking in standard warehouse conditions, maximizing vertical space utilization while maintaining structural integrity.
Will flat-shipped cartons slow down my fulfillment process?
No. Flat boxes assemble in seconds and arrive in a compact footprint, reducing your storage footprint by up to 80% compared to pre-assembled inventory. Most fulfillment operations see faster setup times and better space efficiency with flat-pack delivery.
Are these boxes suitable for hazmat or temperature-sensitive products?
Standard kraft double wall boxes work well for general shipping. For hazmat or temperature-controlled items, consult with our specialists, we offer insulated and certified solutions designed for regulated shipments at competitive volumes.
