Common questions
What ECT rating does this mailer have and why does it matter?
ECT-32-B provides 32 pounds per inch of edge crush test strength. This rating ensures your mailer resists crushing during stacking, conveyor handling, and transit, critical for protecting fragile items and maintaining shipment integrity in high-volume operations.
How much labor and material cost does the fold-and-tuck design save?
No tape, glue, or staples eliminates consumable costs and assembly time. Operators can close each mailer in seconds by hand, reducing fulfillment labor by 30-40% compared to tape-sealed alternatives and eliminating equipment maintenance.
How much warehouse space and freight cost do I save with flat-pack storage?
Flat-packed mailers reduce warehouse footprint by up to 85% compared to pre-assembled boxes. This translates to lower storage costs and significant freight savings on bulk orders, a bundle of 50 ships in a fraction of the cubic space of assembled mailers.
Can I stack these mailers on a pallet, and how many fit per pallet?
Yes. ECT-32-B corrugated supports stacking without collapse. Standard pallet configurations accommodate 20-30 bundles of 50 (1,000-1,500 units per pallet), depending on your stacking height and warehouse equipment.
