Common questions
What does ECT-32 mean and why does it matter?
ECT-32 indicates 32 pounds per inch edge crush strength, a measure of how much vertical pressure the corrugated can withstand before crushing. ECT-32-B dual-wall construction is suitable for small parcels under 5 lbs and provides drop and stacking performance versus single-wall alternatives.
Do these mailers require tape, glue, or staples?
No. The one-piece fold-and-tuck design self-locks when folded, eliminating tape, adhesive, and fasteners. This cuts assembly labor by 60% and reduces per-unit material cost.
What's the dimensional weight advantage of the 332" size?
At 332", dimensional weight calculates to only 0.75 lbs using standard 166 DIM factor, making this ideal for lightweight items. Compared to larger mailers, you save 30, 50% on parcel postage and ground shipping per unit.
Can these mailers be stacked efficiently in the warehouse?
Yes. Flat-packed bundles stack 15, 18 high per case and 80+ cases per standard pallet, optimizing storage footprint and picking efficiency. Pre-assembly is not required, eliminating staging area clutter.
