Common questions
What does ECT-48 rating mean, and why does it matter for my shipping operations?
ECT (Edge Crush Test) 48 means each box can withstand 48 pounds of crushing force per linear inch of flute direction. This rating ensures boxes maintain structural integrity under stacked weight in warehouses and during transit, reducing product damage, insurance claims, and costly replacements, critical for high-velocity fulfillment centers.
How much freight and storage space can I save with these 6x6x48 boxes?
The tall 48" height maximizes pallet cube utilization, allowing you to stack more units vertically per pallet while reducing overall freight weight. Flat-shipped bundles save ~40% warehouse storage versus pre-assembled boxes. At scale (1000+ boxes/month), you'll see 15-25% reduction in LTL shipping costs and warehouse space requirements.
Are these boxes suitable for heavy or fragile items?
Yes. Double wall ECT-48 corrugated provides puncture resistance and crush strength for both heavy industrial products and fragile goods. The kraft material adds moisture resistance, making these boxes ideal for products at risk of damage during handling, stacking, or multi-leg shipping.
How many boxes are in each bundle, and what's the minimum order?
Each bundle contains 15 flat-shipped cartons. Bundles are sold as SKU units, allowing you to order in increments of 15 for predictable inventory management and volume-based pricing that rewards larger commitments.
