The 9 x 11 1/2 inch Kraft Stayflats® Mailer is a rigid, self-sealing flat mailer constructed from .036 kraft chipboard. Built-in stiffness eliminates the need for additional inserts or padding boards, and the tab lock closure seals securely without tape, reducing pack-out steps at the shipping station.
These mailers are well-suited for documents, photographs, prints, certificates, artwork, and other flat or semi-rigid items that must arrive unbent. Print distributors, e-commerce fulfillment centers, legal and professional services firms, and photography studios rely on this format for consistent, presentation-quality delivery of flat contents.
Cases contain 100 mailers and weigh approximately 21.24 lbs, supporting high-volume inventory stocking and predictable per-unit cost management.
