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 can withstand 32 pounds of crushing force per linear inch, making it ideal for small packages stacked on pallets or in shipping containers. This rating ensures products reach customers undamaged while keeping material costs competitive for high-volume operations.
How much faster is the fold-and-tuck design versus traditional taped boxes?
Operators can fold and close these mailers in 2, 3 seconds with zero assembly materials required. Eliminating tape, glue, and staples reduces labor per unit by approximately 40% compared to standard boxes, directly improving your fulfillment throughput.
Will these mailers work for heavier items or just lightweight products?
ECT-32-B corrugated is rated for small-to-medium weight items (typically under 15 lbs per box). The double-wall construction front and sides provides crush resistance for stacking stability, but we recommend confirming your specific item weights with our logistics team for optimal box selection.
What's the freight savings impact of using these versus standard corrugated boxes?
The compact 774" footprint and flat-shipped bundle format reduce inbound freight costs by 35, 50% versus assembled boxes. Additionally, lighter corrugated (32-B) vs. heavier grades cuts outbound dimensional weight charges by 15, 25% on typical small-parcel shipments, compounding savings across volume orders.
