Common questions

What is ECT-32-B and why does it matter for my shipping operation?
ECT (Edge Crush Test) measures corrugated strength; 32-B indicates 32 lbs/inch crush resistance with B-flute construction. This rating ensures reliable stacking performance in warehouses and transit, reducing product damage claims and returns while maintaining cost efficiency for mid-weight items.
How much labor time do I save compared to tape-sealed boxes?
The fold-and-tuck design assembles in 2-3 seconds per mailer with zero tape, glue, or staples. For a 500-unit monthly volume, you save approximately 25-30 labor hours versus traditional sealed boxes, reducing fulfillment costs by 15-20%.
Can these mailers handle stacking during storage and transit?
Yes. ECT-32-B corrugated with double-wall construction supports stable stacking up to 15 boxes high under typical warehouse conditions. The crush-resistant design maintains structural integrity across freight and storage cycles, protecting your ROI.
Are these mailers suitable for heavy or bulky products?
These 7x4x4 mailers are optimized for lightweight to mid-weight items (under 10 lbs). For heavier products, we recommend ECT-44 rated boxes or larger dimensions to ensure crush resistance and compliance with freight safety standards.
