Common questions
What is ECT-32-B and why does it matter for my shipping operation?
ECT-32-B refers to Edge Crush Test rating of 32 lbs/inch, the material's resistance to compression. This double-wall kraft corrugated provides protection for fragile items while remaining lightweight, directly reducing dimensional weight surcharges from FedEx, UPS, and USPS parcel networks.
How much warehouse space do I save with flat-pack storage?
Flat-packed mailers occupy approximately 80% less space than pre-assembled boxes. A single pallet holds significantly more units, enabling smaller safety stock footprints and faster order fulfillment cycles, critical for high-volume warehouses optimizing cubic capacity.
Can these mailers be customized or branded?
Standard kraft color ships immediately for fastest delivery. Custom printing and branding options are available through Packrift's custom services, contact your account manager for pricing and MOQ details.
Are these USPS or carrier-compliant for shipping?
Yes. ECT-32-B kraft corrugated mailers meet or exceed USPS, FedEx, and UPS durability standards for Ground and Priority Mail services. Double-wall construction ensures items arrive protected, reducing damage claims and returns.
