Common questions
What does ECT-32-B mean, and why does it matter for shipping?
ECT (Edge Crush Test) 32-B indicates 32 pounds per inch of crush resistance, meeting industry standards for light-to-medium duty shipping. This rating ensures your mailers protect items during stacking, transit, and handling while remaining cost-effective for high-volume operations.
How quickly can team members assemble these mailers?
One-piece fold-and-tuck design requires no tape, glue, or staples, operators assemble each mailer in 3-5 seconds. This significantly reduces labor costs compared to traditional glued boxes, ideal for warehouse workflows requiring speed and consistency.
Will these mailers reduce my shipping costs?
Yes. The 7x7x6" dimensions minimize dimensional weight surcharges on UPS and FedEx, while the lightweight corrugated construction reduces overall package weight. Combined with no-waste assembly, customers typically see 8-12% shipping cost reduction per 50-unit bundle.
Can these boxes stack during storage and on trucks?
Absolutely. ECT-32-B construction supports stacking when flat or assembled, with crush resistance maintaining integrity under typical warehouse and freight conditions. When stacked flat, 50 unassembled mailers occupy minimal pallet space, optimizing inventory turnover.
