Common questions
What does ECT-32-B mean, and how does it compare to other corrugated ratings?
ECT (Edge Crush Test) -32 indicates the mailer withstands 32 pounds of force per linear inch before crushing. ECT-32-B is standard for lightweight shipments and small-item protection; it's ideal for items under 5 lbs and provides excellent stacking performance in typical warehouse conditions.
How much can I save on postage using these mailers instead of rigid boxes?
The 61/2 21/2 1" dimension minimizes dimensional weight penalties with most carriers (USPS, UPS, FedEx). Compared to larger boxes, you'll reduce billable weight by 40, 60% for similarly sized items, translating to $0.30‚$0.75 savings per unit at scale.
Do these mailers require tape or glue to seal?
No. The one-piece fold-and-tuck design interlocks without tape, glue, or staples. This speeds pack time by 3, 5 seconds per unit and eliminates material waste, critical for high-throughput operations processing 500+ units daily.
Can these mailers be stacked in a warehouse without crushing the contents?
Yes. ECT-32-B corrugated with double-wall construction on front and sides provides crush resistance for up to 6, 8 units stacked vertically. For heavier stacking requirements, consult load testing data or upgrade to ECT-44 variants.
