Common questions
What does ECT-32-B rating mean and why does it matter?
ECT (Edge Crush Test) 32-B indicates the mailer withstands 32 pounds of force per linear inch before failure, with B-flute construction. This ensures consistent crush resistance during stacking, sorting, and transit, critical for protecting contents and maintaining package integrity in high-volume warehouse environments.
How much can these mailers reduce shipping costs compared to rigid boxes?
The lightweight construction and compact 5x4x2 footprint minimize dimensional weight charges. Compared to rigid boxes, these mailers typically save 15-25% on postage per unit while the fold-and-tuck design eliminates tape, glue, and labor costs associated with assembly.
Can these mailers be stacked safely in a warehouse?
Yes. The ECT-32-B rating and double-wall construction provide reliable stacking strength for warehouse storage. When properly stacked, these mailers maintain structural integrity and protect contents from compression damage during inventory holds.
Do these require any assembly tools or materials?
No. The one-piece fold-and-tuck design requires no tape, glue, staples, or tools. Simply fold and secure, use for high-speed fulfillment operations seeking to maximize throughput and reduce labor overhead.
