Frequently bought with

Common questions

What does ECT-32-B mean and how does it affect stacking strength?
ECT (Edge Crush Test) 32-B indicates 32 lbs per inch of edge crush strength with B-flute corrugation. This provides reliable stacking performance for multi-tier pallet configurations and protects contents during handling and transit without excessive material cost.
How much warehouse space do these save compared to pre-assembled boxes?
One-piece mailers ship and store flat, reducing storage footprint by up to 90% versus pre-assembled alternatives. A bundle of 50 mailers occupies minimal warehouse real estate while maintaining crush resistance and protection performance.
Can I use these mailers without tape or additional packaging materials?
Yes. The fold-and-tuck design creates secure double-wall construction on front and sides without tape, glue, or staples. Mailers assemble in seconds and seal tight enough for fragile items, reducing material costs and assembly labor.
What shipping weight advantage do these kraft mailers provide?
Lightweight kraft corrugated construction minimizes dimensional weight charges on parcel carriers like UPS and FedEx. The 9x6x4" size qualifies for lower postage tiers for small items, reducing per-unit shipping costs across high-volume orders.
