Common questions
What does ECT-32-B rating mean for my shipping operations?
ECT (Edge Crush Test) 32-lbs indicates the corrugated can resist 32 pounds of crushing force per linear inch. This double-wall construction ensures fragile items survive multi-box stacking during storage and transit, reducing damage claims and customer returns, critical for protecting margin on high-velocity SKUs.
How much assembly labor do I save with the fold-and-tuck design?
One-piece mailers fold together in seconds without tape, glue, or staples. On a 500-unit daily volume, you'll save 2, 3 labor hours per shift compared to traditional tape-sealed boxes, directly reducing fulfillment cost per order by $0.05‚$0.08 per unit.
Will these fit standard pallet configurations for my warehouse?
Yes. The compact 71/2" 31/4" 1" footprint is optimized for e-commerce parcel sorts and regional carrier pallets. Flat bundles of 50 stack efficiently in warehouse racking, and folded mailers compress to maximize pallet cube utilization during shipping.
Can I customize or print branding on these mailers?
Standard white mailers support flexographic and digital printing. Contact our sales team for minimum order quantities on custom print runs, ideal for branded unboxing experiences that increase customer retention without bulk inventory commitments.
