Frequently Asked Questions
ECT (Edge Crush Test) -32-B indicates 32 lbs per inch of crush resistance with B-flute corrugation. This mid-tier rating protects lightweight to medium-weight items from compression damage during stacking and transit, balancing protection with material cost efficiency for typical small-parcel operations.
One-piece fold-and-tuck design eliminates taping, gluing, or stapling steps, reducing packing time by 15-30 seconds per box. For high-volume operations packing 500+ units daily, this saves 2-4 hours of labor per shift while improving consistency and reducing material waste.
Yes. The lightweight ECT-32-B corrugated construction minimizes dimensional weight impact compared to heavier corrugate alternatives. For parcel carriers charging by dimensional weight, this translates to 5-12% freight savings on typical small-parcel shipments.
The double-wall crush-resistant design with ECT-32-B rating provides solid protection for fragile items when paired with internal cushioning (foam, air pillows, or paper fill). We recommend additional void fill for maximum damage prevention on high-value or delicate products.
