Common questions

What does ECT-32-B mean, and how does it impact crush resistance?
ECT (Edge Crush Test) 32 indicates the mailer can withstand 32 lbs of force per linear inch. The B-flute corrugated construction creates double walls on the front and sides, ensuring reliable crush protection for fragile items during transit and stacking in the warehouse.
How much time do we save with no-tape assembly?
One-piece fold-and-tuck design eliminates the need for tape, glue, or staples, reducing packing labor by 15-20 seconds per box. For high-volume fulfillment operations, this translates to significant daily labor savings across thousands of shipments.
Can these mailers be stacked safely during storage?
Yes. The ECT-32-B corrugated material provides excellent stacking strength. When shipped flat, the mailers compress efficiently for warehouse storage; when assembled, they maintain structural integrity under normal warehouse stacking conditions.
What's the postage advantage compared to rigid boxes?
The lightweight kraft construction reduces dimensional weight charges with USPS, UPS, and FedEx. The compact 8 x 3 x 3" footprint also minimizes cubic footage, lowering freight costs on LTL and parcel shipments compared to heavier rigid alternatives.
