Common questions
What does ECT-32 mean, and why does it matter for my shipping operation?
ECT (Edge Crush Test) rating of 32 indicates the mailer can withstand 32 pounds of force per linear inch before crushing. This rating ensures reliable stacking performance in warehouses and during transport, reducing product damage and costly returns, critical for high-velocity fulfillment centers.
Can these mailers replace my current tape-sealed boxes and reduce labor?
Yes. The one-piece fold-and-tuck design requires no tape, glue, or staples, cutting packing time by 30-50% per unit. Warehouse teams can assemble boxes in seconds, freeing labor for other fulfillment tasks and improving throughput during peak seasons.
How do these mailers perform when stacked in a warehouse or on a pallet?
The ECT-32-B corrugated construction and double-wall protection on front and sides provide excellent stacking stability. These mailers support vertical compression without collapsing, allowing you to maximize pallet density and reduce cubic waste in your warehouse footprint.
What shipping cost savings can I expect using these lighter mailers?
Lightweight design reduces dimensional weight surcharges and per-unit postage costs, especially for small parcel carriers. Volume buyers shipping 1,000+ units monthly typically see 8-15% freight savings compared to heavier corrugated or plastic alternatives.
