Common questions
What does ECT-32 rating mean and why does it matter for my warehouse?
ECT-32 refers to the Edge Crush Test rating of 32 pounds per inch, the standard measure of how much vertical load a corrugated box can support. Higher ECT ratings mean better stacking performance in your warehouse, reducing product damage during storage and transport. ECT-32-B is ideal for small, lightweight items where stack height efficiency matters.
Can I eliminate tape entirely, or do I still need to seal the tuck flaps?
The fold-and-tuck design is engineered to stay closed without adhesives for standard lightweight shipments. However, if your items are particularly heavy or will experience aggressive handling, we recommend a single strip of packaging tape on the tuck seam for added security.
How many of these fit on a standard pallet, and what's the volumetric advantage?
A bundle of 50 flat-packed mailers occupies minimal space, allowing you to store approximately 50-60 bundles per pallet. When assembled, the one-piece fold-and-tuck design uses less interior void space than two-piece boxes, improving your dimensional weight pricing on carrier invoices.
Is this box suitable for heavier items, or should I upgrade to a higher ECT rating?
ECT-32-B is rated for lightweight items up to approximately 10 lbs depending on content density and stacking conditions. For heavier or more fragile shipments, consider upgrading to ECT-44 or ECT-51 corrugated mailers to maintain crush resistance and reduce damage-related chargebacks.
