Kraft Stayflats® Mailers in the 17 x 21 inch size are constructed from .036 kraft chipboard, delivering rigid, self-contained flat protection without insert boards or supplemental stiffeners. The board material maintains contents flat against bending and crushing through the full handling and transit cycle.
The tab lock closure seals the mailer without tape or additional fasteners, accelerating pack-out in high-volume fulfillment centers, print distributors, and retail replenishment operations. The lightweight chipboard construction helps control postage and carrier costs across parcel and mail channels, making these mailers practical for both low-volume boutique shippers and large outbound operations alike.
Each mailer ships parcel-friendly. Cases contain 50 mailers, supporting accurate inventory planning and predictable cost-per-unit purchasing at scale.
