Common questions
What does ECT-32-B rating mean for my shipping operation?
ECT-32-B indicates 32-pound edge crush test strength with B-flute corrugation, ideal for small, lightweight packages. This rating provides excellent crush resistance for fragile items without excess weight that increases postage costs.
How quickly can staff assemble these mailers during peak fulfillment?
One-piece fold-and-tuck design requires only 2-3 seconds per mailer with zero tools or adhesives needed. A single operator can prepare 1,200+ units per hour, significantly reducing labor time versus traditional boxes requiring tape and assembly.
What's the freight and storage advantage of flat-ship design?
Flat storage reduces your inbound receiving footprint by approximately 85-90% versus pre-assembled mailers. When multiplied across bulk orders, this translates to lower freight-in costs, reduced warehouse racks needed, and faster inventory turnover.
Are these mailers suitable for e-commerce returns and two-way shipping?
Yes, ECT-32-B kraft construction withstands repeat handling, making these ideal for subscription boxes, returns processing, and multi-leg shipping scenarios. The double-wall design on critical surfaces protects contents through multiple carrier transitions.
