Common questions
What does ECT-32-B mean, and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32-B indicates your mailer withstands 32 pounds per inch of edge crush force with B-flute corrugation. For B2B fulfillment, this means reliable crush resistance during stack-and-ship workflows, reducing damage claims and returns while keeping postage fees competitive due to lightweight construction.
Do I need tape, glue, or staples to close these mailers?
No. The one-piece fold-and-tuck design closes securely without any adhesives or fasteners. Simply fold the flaps together, this reduces assembly time per box by 15-30 seconds compared to tape-sealed alternatives, significantly improving throughput in high-volume operations.
How much freight weight and space do 50 mailers save compared to rigid boxes?
Flat-packed corrugated mailers reduce inbound freight weight and cube by 60-70% versus rigid boxes. One pallet of flat mailers equals 8-10 pallets of pre-assembled boxes, directly lowering your inbound logistics costs and maximizing warehouse storage density.
Are these mailers suitable for stacking during warehouse operations?
Yes. When folded closed, the double-wall construction on front and sides provides excellent stacking performance, supporting multiple units vertically without deformation. This supports lean inventory management and vertical storage optimization in fulfillment centers.
