Frequently bought with

Common questions

What does ECT-32-B mean, and how does it affect durability?
ECT-32-B indicates 32 ECT (Edge Crush Test) rating with B-flute corrugation. This delivers reliable crush resistance for small to mid-weight items while maintaining lightweight characteristics that reduce postage costs. Ideal for items under 2 lbs.
How much time does the fold-and-tuck design save compared to traditional mailers?
One-piece fold-and-tuck construction eliminates tape and assembly steps, reducing prep time by approximately 45-60 seconds per box. At scale, this translates to significant labor savings across high-volume fulfillment operations.
Can these mailers stack efficiently in a warehouse?
Yes. The flat, folded format maximizes storage density and stackability. A bundle of 50 occupies minimal shelf space, enabling better inventory management and reducing your overall warehouse footprint compared to pre-assembled boxes.
Are these mailers suitable for fragile items?
Absolutely. The double-wall construction on front and sides provides crush resistance, protecting fragile items like glass, electronics, and cosmetics. The enclosed design also prevents shifting during transit, reducing damage claims and returns.
