Common questions
What does ECT-32-B mean, and how does it impact shipping protection?
ECT-32-B indicates Edge Crush Test of 32 pounds per inch, a measure of the box's ability to resist crushing under vertical pressure. This rating ensures reliable protection for small, fragile items without over-engineering, keeping your per-unit cost competitive while meeting quality standards for most small parcel shipments.
Do these mailers require assembly time, tape, or additional materials?
No. These one-piece fold-and-tuck mailers assemble in seconds with no tape, glue, or staples needed. Your fulfillment team can pack and seal items faster, reducing labor costs and improving throughput in high-volume environments.
How much warehouse space do these save compared to pre-assembled boxes?
Because they ship and store completely flat, you can store 10-15x more mailers in the same cubic footage compared to pre-assembled boxes. For warehouse managers handling high volumes, this translates to significant storage cost savings and better inventory turnover.
What types of products work best in a 7 x 3 x 3" mailer?
This size is ideal for small, lightweight items: tools, glassware, electronics, cosmetics, small parts, and fragile goods that fit comfortably in the 7" length. The double-wall construction protects contents during transit while the compact dimensions keep postage and freight costs minimal.
