Common questions
What does ECT-32 mean and why does it matter for stacking?
ECT (Edge Crush Test) 32 indicates the corrugated material can withstand 32 pounds of force per linear inch when compressed edge-down. This rating ensures safe multi-level stacking in warehouses and on pallets, protecting both product integrity and worker safety during fulfillment operations.
Can I use these boxes instead of mailing tubes for long items?
Yes. The 4x4x30" tall profile accommodates items traditionally shipped in tubes while offering protection, easier labeling and barcode placement, and better dimensional weight pricing with most carriers. The square footprint also stacks more efficiently than round tubes.
How many boxes fit on a standard pallet?
When assembled and stacked, approximately 60-80 boxes fit on a 48x40" pallet depending on your stacking height constraints. The narrow 4x4" base maximizes pallet density compared to wider carton formats, directly reducing your per-unit freight cost.
Are these boxes suitable for heavy items or only lightweight merchandise?
ECT-32 single-wall is rated for lightweight to medium-weight items (typically up to 15-20 lbs per box depending on content density and stacking configuration). For heavier tall items, consider ECT-44 double-wall variants. Contact our specialists to verify your specific load requirements.
