Common questions

What ECT rating means and why it matters for my shipping operation?
ECT-32-B indicates Edge Crush Test of 32 pounds per inch width, sufficient for small parcel applications under 5 pounds. This rating ensures your boxes maintain structural integrity during stacking and transit, reducing damage claims while keeping material costs lower than heavier ECT ratings.
How does the one-piece mailer design improve packing efficiency?
Fold-and-tuck construction eliminates assembly steps and eliminates need for tape, glue, or staples. Your team closes each box in seconds with one motion, reducing labor time per shipment by up to 40% compared to traditional two-piece boxes while maintaining double-wall protection.
Can this 9x6x4 mailer help me reduce dimensional weight charges?
Yes. The compact footprint minimizes dimensional weight calculations with carriers like FedEx and UPS. Bundling multiple small items in this size instead of larger boxes directly reduces per-unit shipping costs, improving margin on small-item orders.
Is this mailer suitable for fragile items?
Yes. The double-wall corrugated construction on front and sides provides excellent crush resistance for lightweight fragile goods like glassware, electronics, and cosmetics. For heavier fragile items or items requiring void fill, pair with appropriate internal protective materials.
