Frequently bought with

Common questions

What is ECT-32-B and why does it matter for my operation?
ECT-32-B (Edge Crush Test) indicates the corrugated can support 32 lbs of pressure per linear inch. This rating ensures boxes won't collapse under stacking weight in warehouses or during transport, protecting merchandise and reducing damage claims that impact your bottom line.
How much time do I save with the fold-and-tuck design?
No tape, glue, or staples means operators assemble boxes in seconds versus 10, 15 seconds per box with traditional taped cartons. At scale, a team shipping 500+ units daily saves 1, 2 labor hours per shift while reducing material waste.
Will these mailers reduce my postage costs?
Yes. At just 9 x 4 x 4 inches with crush-resistant ECT-32-B construction, you maximize dimensional weight efficiency. Lighter-weight corrugated versus solid cardboard lowers per-unit postage, and the compact format qualifies for regional carrier discounts.
Are these mailers stackable in our fulfillment center?
Absolutely. The double-wall construction on front and sides provides crush resistance, allowing safe stacking of filled mailers 4, 6 units high. This design maximizes vertical storage in pick-and-pack zones without damage risk.
