Common questions

What is the ECT rating and why does it matter for my warehouse?
ECT-32-B means 32 pounds per inch of edge crush strength. This rating ensures your mailers resist collapse and stacking damage during transit and warehouse handling. For typical small parcel applications, ECT-32 provides optimal crush resistance while maintaining cost efficiency and competitive postage rates.
How much labor time do I save with no-tape assembly?
One-piece fold-and-seal design eliminates taping steps entirely, boxes assemble in 2-3 seconds per unit with zero additional materials. For high-volume operations (1,000+ boxes/day), this reduces labor cost by 30-40% compared to traditional taped cartons.
Will these mailers stack safely during shipping and storage?
Yes. ECT-32-B corrugated provides reliable stacking performance up to 5-6 boxes high under standard warehouse conditions. The crush-resistant construction maintains structural integrity even with full pallet loads, protecting contents and reducing damage claims.
Can I order these in bulk for volume discounts?
Absolutely. These mailers are sold in bundles of 50 and scale efficiently for palletized bulk orders. Contact your Packrift account manager to discuss volume pricing for 5,000+ unit orders and custom freight consolidation options.
