Common questions

What does ECT-32 mean and why does it matter?
ECT-32 (Edge Crush Test rating of 32) indicates the kraft corrugated can withstand 32 lbs of crushing force per linear inch. This rating ensures reliable protection for small packages during sorting, stacking, and transit, critical for B2B fulfillment where handling is intensive.
How much can I save by switching from assembled boxes?
Flat-ship mailers reduce freight costs 30-40% versus pre-assembled boxes, save 85% warehouse storage space, and eliminate labor for box assembly. A typical fulfillment center ships 50,000+ units monthly, the savings compound significantly.
Do these mailers require tape or other materials?
No. The one-piece fold-and-tuck design locks securely without tape, glue, or staples. Assembly takes 2-3 seconds per mailer, reducing packing labor and material costs while maintaining crush resistance.
Are these mailers suitable for fragile items?
Yes. The ECT-32-B kraft corrugated provides double-wall protection on the front and sides, designed specifically for fragile goods like glassware, ceramics, and tools. Internal cushioning materials (not included) can be added for additional protection.
