Common questions
What does ECT-32-B mean, and how does it impact mailer performance?
ECT (Edge Crush Test) rating of 32 pounds per inch indicates the mailer's crush resistance under stacking loads. ECT-32-B provides reliable protection for moderate-weight items while maintaining cost efficiency, ideal for small parcel operations where pallets are stacked 4-6 units high in distribution centers.
How much weight can I safely stack with these mailers?
ECT-32-B mailers support approximately 200-300 lbs of stacking weight per square inch depending on pallet configuration and warehouse storage duration. For high-density storage exceeding 5 units stacked, consult weight distribution guidelines or upgrade to ECT-44 if handling heavier SKUs.
Do these require tape, glue, or staples to assemble?
No. The one-piece fold-and-tuck design features pre-scored panels that close in seconds with hand pressure alone. This eliminates tape, glue, and staples, reducing assembly time by up to 40% versus traditional tape-sealed boxes and cutting consumable costs.
How much postage savings does the 9 x 3 x 3 compact size provide?
Compared to standard 12 x 6 x 6 mailers, this compact size reduces dimensional weight by approximately 30-45%, directly lowering per-unit USPS, UPS, and FedEx postage charges, a significant savings lever for high-volume e-commerce fulfillment operations processing thousands of monthly shipments.
