Common questions

What does ECT-32-B mean, and how does it compare to thinner corrugated?
ECT-32-B indicates 32-pound edge crush test rating with B-flute corrugation, the standard for mid-weight protective shipping. This rating supports stacking heights of 48-60" in typical warehouse conditions, outperforming 200# and 225# kraft in crush resistance while maintaining lighter weight for postage savings.
Do these mailers require tape, glue, or staples?
No. The one-piece fold-and-tuck design features pre-scored creases and locking flaps that secure without adhesives. This reduces labor time per box by 60-70% compared to traditional FEFCO designs and eliminates supply chain dependencies on tape inventory.
What is the maximum stacking load for these 9x3x3 mailers on a pallet?
ECT-32-B supports 4-5 pallets high in a 48-high warehouse environment under static load (full boxes). For dynamic conditions and freight vehicles, stack to 3 pallets high maximum. Conduct load testing with your specific product weight to confirm capacity.
How many 9x3x3 mailers fit on a standard 48x40" pallet?
A single bundle (50 mailers) ships flat and occupies approximately 1-1.5 cubic feet. Estimate 60-80 bundles per pallet depending on secondary packaging. This density supports 3,000-4,000 individual mailers per pallet, significantly reducing per-unit freight cost at volume.
