Kraft Stayflats® Mailers in the 13 x 18 inch size are rigid chipboard mailers built to keep flat contents unbent and protected in transit. Constructed from .036 kraft chipboard, each mailer delivers firm flex resistance without requiring supplemental stiffeners, eliminating an extra step from the packing process.
The tab lock closure secures contents without tape or adhesive strips, supporting efficient throughput in high-volume fulfillment environments. These mailers are well-suited for documents, prints, photographs, original artwork, presentation boards, and oversized certificates — applications common in print shops, photography studios, legal offices, and promotional product distributors.
The lightweight chipboard construction keeps per-unit postage costs manageable across large send volumes. Available in cases of 100, they are practical to stock for operations that process consistent flat-item shipments at scale.
