ECT (Edge Crush Test) 32-B indicates the corrugated can withstand 32 lbs of pressure per linear inch, sufficient for most lightweight parcels. This mid-range rating balances durability with cost efficiency, making it ideal for high-volume shippers prioritizing freight savings over maximum protection.
At approximately 0.35 oz per mailer, the lightweight construction minimizes dimensional weight penalties. For carriers using DIM divisors of 166-200, this translates to lower billable weight and measurable cost reductions on high-volume accounts.
Yes. The double-wall construction on front and sides resists crushing during stacking. A bundle of 50 flat mailers occupies minimal floor space, and assembled boxes can stack 4-5 high when empty without deformation, maximizing storage efficiency.
No. The fold-and-tuck design requires zero equipment, simply fold, tuck the flaps, and seal if needed. Most warehouse staff assemble these in under 5 seconds per box, reducing labor bottlenecks in fulfillment operations.
