Common questions
Do these mailers require assembly time or special equipment?
No. The fold-and-tuck design assembles in seconds by hand, no tape, glue, staples, or machinery needed. This reduces fulfillment labor and allows your team to ship faster.
Will these protect documents during shipping?
Yes. ECT-32-B corrugated kraft provides crush-resistant protection for standard documents, catalogs, and literature up to 1/8" thickness. The rigid structure safeguards contents through typical shipping conditions.
Are these mailers suitable for retail product inserts or promotional materials?
Absolutely. The 9 x 6 1/4 x 4" size accommodates most marketing materials and promotional inserts while maintaining a professional kraft appearance that enhances brand perception at unboxing.
Can I use these for documents larger than standard letter size?
These mailers are optimized for standard letter-size documents (8.5" x 11"). For larger materials, folded documents fit within the 9" length. Custom sizes are available for bulk orders.
