Common questions
What does ECT-32-B mean, and why does it matter for my operation?
ECT (Edge Crush Test) 32-B indicates the corrugated board can withstand 32 pounds of force per linear inch. This rating ensures reliable crush resistance for stacked shipments, protecting your products during multi-day transit and storage while maintaining cost efficiency for lightweight items.
Do these mailers require assembly equipment or tape?
No. These one-piece fold-and-tuck mailers assemble by hand in seconds with zero additional materials. Your fulfillment staff can fold and seal without tape, glue, or staples, reducing assembly labor by up to 40% compared to traditional four-flap boxes.
How much warehouse space do I save with flat-packed storage?
Flat-packed bundles of 50 occupy approximately 85% less space than pre-assembled mailers. This translates to measurable cost savings on warehouse rent and faster inventory turnover, especially for high-volume e-commerce operations.
Are these kraft mailers suitable for branded or branded shipments?
Yes. The natural kraft finish supports printing and custom branding through flexographic or digital methods. Double-wall construction and crush-resistant design ensure your brand presentation remains pristine from warehouse to customer doorstep.
