Common questions
What does ECT-32-B rating mean for my shipping operations?
ECT (Edge Crush Test) 32-B indicates the mailer can withstand 32 lbs per linear inch of crush force while stacked in transit. This standard rating is ideal for lightweight packages and provides reliable protection against compression damage in multi-tier pallet loads.
How much labor time do I save with the fold-and-tuck design?
Eliminating tape, glue, and staples reduces pack time by 8-15 seconds per mailer compared to traditional box assembly. For high-volume operations shipping 500+ units daily, this translates to 1-2 hours of labor savings per shift.
Will these mailers reduce my dimensional weight charges?
Yes. At 6 x 3 x 3 inches, these mailers are optimized for parcels under 5 lbs, helping you avoid surcharges on carriers like FedEx and UPS that charge based on the greater of actual or dimensional weight.
Are these mailers compatible with my existing packing line?
One-piece fold-and-tuck mailers fit into manual and semi-automated packing stations. No specialized equipment required, fold, load product, and seal. They stack compactly for efficient bin placement at fulfillment stations.
