Common questions
What does ECT-32-B mean, and how does it compare to other corrugated grades?
ECT (Edge Crush Test) 32-B indicates 32 lbs/inch of edge crush strength with B-flute corrugation, the optimal balance for small, lightweight mailers. This grade provides excellent crush resistance for typical small-package contents while keeping material costs and shipping weight minimal, making it ideal for high-volume fulfillment operations.
How many 7x5x2 mailers fit on a standard pallet, and what's the freight savings?
Flat-pack design allows approximately 60-80 bundles (3,000-4,000 units) per pallet depending on stacking height, compared to 15-20 bundles for pre-assembled mailers. This 3-4x density improvement cuts inbound freight costs per unit and maximizes warehouse storage efficiency.
Do these mailers require tape or adhesive, and what's the assembly time per unit?
No tape, glue, or staples required. The one-piece fold-and-tuck design allows warehouse staff or automated systems to assemble each mailer in 2-5 seconds, eliminating material costs and labor overhead associated with taping or stapling alternatives.
Are these mailers suitable for fragile items, and will contents shift during transit?
Yes. Double-wall corrugated protection on the front and sides resists crushing and provides excellent cushioning for lightweight fragile items like electronics, glassware, and cosmetics. The compact 2" depth and snug fit minimize internal shifting while maintaining dimensional stability throughout the shipping lifecycle.
