Common questions

What does ECT-44 mean, and why does it matter for my shipments?
ECT (Edge Crush Test) measures the load-bearing strength of corrugated cardboard. ECT-44 means this material withstands 44 pounds of force per linear inch, ideal for stacking heavy items or shipping multiple units per box. This rating ensures your products arrive damage-free and reduces costly returns.
How much stronger are these boxes compared to standard corrugated?
These HD999 boxes are 40% stronger than standard single-wall corrugated cartons. This extra durability translates to better product protection, improved pallet stacking performance, and reduced damage claims, delivering measurable savings across your supply chain.
Will these boxes help reduce my shipping costs?
Yes. The compact 9x9x9" dimension maximizes pallet density, reducing per-unit freight costs. Heavy-duty construction also means less void fill material is needed, further cutting packaging expenses. For high-volume shippers, these savings compound quickly across thousands of boxes.
Can I stack these boxes safely during warehouse storage?
Absolutely. ECT-44 kraft corrugated provides excellent vertical stacking strength, allowing safe multi-tier stacking in warehouses and fulfillment centers. This maximizes your storage space utilization while protecting contents from compression damage.
