Common questions
What is the crush rating and how does ECT-32-B perform under stacking?
ECT-32-B provides 32 lbs per inch of edge crush test strength. Double-wall construction on front and sides resists compression from stacking and handling, reducing in-transit damage by up to 40% compared to single-wall alternatives. Ideal for 3-4 box high stacking in standard pallet configurations.
Do these mailers require tape, glue, or assembly equipment?
No. One-piece fold-and-tuck design requires zero adhesives, tape, or staples. Mailers assemble in 2-3 seconds by hand, eliminating equipment costs and reducing labor overhead by 60-70% versus traditional glued cartons. Use for high-volume fulfillment operations.
How much warehouse space do flat-pack mailers save?
Flat-pack storage reduces footprint by 85-90% versus pre-assembled boxes. One pallet of flat 5x5x5" mailers stores up to 4,800 units, equivalent to 8-10 pallets of assembled boxes, lowering inventory carrying costs and improving receiving efficiency.
Are these mailers suitable for fragile items like glassware and electronics?
Yes. Double-wall ECT-32-B kraft corrugated combined with the mailer's 5x5x5" format creates protective cushioning for small fragile items. The crush-resistant design and fold-and-tuck side walls provide 360° structural integrity, reducing claim rates for tools, glassware, and electronics shipments.
