Common questions
What does ECT-32-B mean, and why does it matter for my operation?
ECT (Edge Crush Test) 32-lb rating indicates the mailer withstands 32 pounds of crushing force per linear inch. This mid-grade specification balances protection and cost, making it ideal for lightweight items. It exceeds requirements for items under 5 lbs and reduces per-unit packaging spend versus higher ECT ratings.
How much labor time do these one-piece mailers save versus traditional boxes?
Fold-and-tuck design requires no tape, glue, or staples, reducing assembly time to 3-5 seconds per mailer versus 15-20 seconds for taped boxes. For a 500-unit daily volume, this saves 1.5+ labor hours per day or ~$20 in fulfillment labor costs.
Will these mailers fit my existing conveyor and packing line?
Yes. The compact 61/2 3, Öù 21/2" footprint integrates directly with standard pick-and-pack conveyor systems and fits USPS Priority Mail, UPS Ground, and FedEx 2-day dimensional weight limits. Pre-folded design allows high-speed hand packing.
How do these compare to padded mailers or polywrap alternatives?
Corrugated mailers provide crush resistance and stacking strength versus plastic mailers, support better recyclability (increasing sustainability scores), and cost 20-30% less per unit. Double-wall construction on front/sides protects contents without added film layers, reducing material waste.
