Common questions
What does ECT-32 rating mean and how does it affect my shipping costs?
ECT-32 (Edge Crush Test) indicates the mailer can withstand 32 pounds per inch of edge pressure, providing reliable crush resistance for typical lightweight shipments. The lightweight construction reduces dimensional weight charges compared to heavier corrugated, directly lowering freight costs per unit shipped.
How much assembly time does fold-and-tuck design save vs. traditional mailers?
Operators can assemble these mailers in seconds without tape, glue, or staples, eliminating material costs and reducing manual labor by up to 70% compared to tape-and-glue alternatives. At volume, this translates to significant labor savings across high-throughput fulfillment operations.
Will double-wall protection reduce my product damage claims?
Yes. The double-wall construction on front and sides provides crush resistance and impact absorption during transit and handling. This is especially critical for fragile items, helping reduce damage claims and associated refund/replacement costs.
Can I stack these mailers efficiently on pallets for storage?
The compact 7.5" x 3.5" x 3.25" footprint is optimized for pallet stacking and warehouse density. Flat-shipped bundles allow you to store up to 40 bundles per pallet, maximizing your cubic utilization and reducing inventory footprint costs.
