Common questions
What is the ECT rating and why does it matter?
ECT-32-B means these mailers provide 32 ECT (Edge Crush Test) strength with B-flute corrugation. This rating ensures reliable crush resistance for typical small item shipments, protecting contents during stacking, handling, and transit while maintaining lightweight postage efficiency.
How much can I save on storage with flat-ship mailers?
Flat-shipped mailers occupy approximately 90% less warehouse space compared to pre-assembled boxes. A pallet of 2,500 flat mailers takes up minimal cubic footage, allowing you to stock more inventory in the same footprint and reduce per-unit handling costs.
Do these mailers require assembly equipment or training?
No. These one-piece fold-and-tuck mailers require zero equipment, tape, glue, or staples. Staff can fold and load items in seconds with minimal training, improving fulfillment speed and reducing labor costs per shipment.
What items are best suited for 8 x 6 x 3" mailers?
Ideal for small tools, glassware, jewelry, watches, small electronics, cosmetics, apparel samples, and other items under 3 inches tall. The double-wall construction protects fragile goods while the compact size maximizes postage savings for B2B and B2C operations.
