Common questions
What does ECT-32-B mean and why does it matter for my operation?
ECT-32-B indicates an Edge Crush Test rating of 32 lbs per inch, a strong corrugated grade that handles stacking pressure and freight handling without failure. This rating ensures your shipments stay protected through warehouse handling and transit, reducing damage claims and customer returns.
How quickly can staff assemble these mailers during peak fulfillment?
These one-piece fold & tuck mailers require zero assembly time, no tape, glue, or staples needed. Staff simply fold along scored lines, which takes seconds per mailer, dramatically improving throughput during high-volume shipping periods and reducing labor costs per unit.
Will these mailers crush under stacking in my warehouse?
No. The double-wall corrugated construction activates when folded, creating crush-resistant protection on front and sides. The ECT-32-B rating supports reliable stacking performance, making these ideal for bulk storage and reducing damage from vertical warehouse pressure.
Can I use these for lightweight fragile items without additional void fill?
Yes. The double-wall protection and crush-resistant design provide robust cushioning for small fragile items like electronics, cosmetics, and glassware. For maximum protection, minimal void fill (crinkle paper or air pillows) is recommended, but the mailer construction handles lightweight fragiles effectively.
