Common questions

What does ECT-32-B mean, and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32-B indicates the corrugated material can withstand 32 pounds of crushing force per linear inch. This rating ensures reliable stacking strength and crush resistance for small packages, protecting contents during handling while maintaining lightweight characteristics that reduce postage expenses.
How much warehouse space and shipping cost can I save with flat-shipped mailers?
Flat-shipped mailers reduce storage cubic footage by up to 70% compared to pre-assembled boxes and lower dimensional weight charges on parcel carriers. A bundle of 50 flat mailers occupies minimal space, allowing you to stock more inventory per cubic foot and decrease overall freight costs.
Can these mailers be assembled quickly in a fulfillment workflow?
Yes. Each one-piece mailer folds and tucks together in seconds with no tape, glue, or staples required. This tool-free design accelerates packing operations, reduces labor costs, and minimizes assembly errors in high-volume fulfillment environments.
Are kraft corrugated mailers suitable for fragile items like glassware and electronics?
Yes. The double-wall crush-resistant construction of ECT-32-B corrugated kraft provides excellent protection for fragile items. Combined with proper void fill, these mailers effectively protect tools, glassware, small electronics, and other breakables during transit and handling.
