Common questions
What is ECT-32-B and why does it matter for my operation?
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.
How much does this mailer weigh and will it impact my shipping costs?
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.
Can I stack these mailers in my warehouse without crushing them?
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.
Do I need special equipment or training to assemble these?
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.
