Common questions
What does ECT-32-B mean and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32-B indicates the corrugated material can withstand 32 pounds per inch of edge crush force with a B-flute profile. This mid-range rating provides excellent crush resistance for standard small packages while keeping material costs competitive, ideal for high-volume fulfillment where cost-per-unit directly impacts margins.
How much labor time does the fold-and-tuck design save versus traditional taped boxes?
Operators can assemble and seal these mailers in under 5 seconds with zero consumables (no tape, glue, or staples required). For fulfillment centers processing 500+ boxes daily, this eliminates thousands of dollars in labor and tape costs annually while reducing assembly errors.
Will these mailers meet my freight weight targets for postage optimization?
Yes. ECT-32-B corrugated is engineered to be lightweight without sacrificing protection, meaning your dimensional weight and actual weight stay optimized. The compact 6.19" x 5.38" footprint also qualifies for lower postage tiers with USPS, UPS, and FedEx.
Can I stack these mailers in storage without crushing the contents?
Absolutely. The double-wall crush-resistant construction on the front and sides provides stacking strength when bundled. This allows efficient warehouse stacking up to 8-10 bundles high without damage, maximizing vertical storage and reducing your facility footprint.
