Frequently Asked Questions

ECT (Edge Crush Test) -32-B indicates 32 pounds per inch of edge crush strength, meeting FEFCO standard for lightweight corrugated. This rating provides adequate stacking performance for 6-8 pallet heights while keeping mailers lightweight, reducing dimensional weight charges by 12-18% versus thicker alternatives on carriers like FedEx and UPS.

Operators can assemble and close these mailers in 8-12 seconds per unit with zero tape or adhesive, versus 25-35 seconds for traditional boxes. For a 1,000-unit daily volume, this saves approximately 4-5 labor hours per day, translating to $200-300 daily labor cost reduction at standard warehouse wages.

These mailers are optimized for items under 3 pounds. The double-wall corrugated construction on front and sides provides excellent crush protection for fragile items like electronics, cosmetics, and collectibles. For items over 3 pounds or high-impact shipping, consider ECT-44-B or rigid-wall alternatives.

Standard 50-unit bundles ship in plain white. Custom printing with logos, return addresses, or promotional messaging is available on orders of 250+ bundles with 2-3 week lead times. Contact our B2B sales team for custom quote and minimum order requirements.
