Common questions

What is ECT-32-B and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32-B means these mailers withstand 32 lbs per inch of edge crush force. This rating ensures your packages stay protected during handling, conveyor processing, and stacking in warehouses, reducing damage claims and returns.
How much labor time do I save with one-piece fold-and-tuck design?
Operators can assemble and seal these mailers in 3-5 seconds without tape, glue, or staples. For a 500-box daily volume, you'll save approximately 30-40 minutes per shift compared to traditional taped boxes.
Will these mailers fit my small item inventory?
Yes. The 5 x 4 x 4" interior dimension is optimized for items under 5 lbs, including electronics, cosmetics, jewelry, clothing, and books. Double-wall construction protects fragile contents without excessive dimensional weight charges.
How do these mailers reduce my shipping costs?
Lightweight corrugated construction lowers DIM weight charges on UPS, FedEx, and USPS. Bundled pricing at 50 units per pack also reduces per-unit cost by 15-25% versus case quantities, directly improving your margin on small-parcel shipments.
