Kraft Stayflats® Mailers in the 11 x 13-1/2" size are built from .036 kraft chipboard, delivering rigid, flat protection without additional stiffeners or inserts. The integrated tab lock closure secures contents during transit without tape, reducing pack-out time and materials at the point of fulfillment.
This size suits e-commerce retailers, print distributors, and direct-mail operations shipping documents, photographs, artwork, apparel, and other flat goods that must arrive without bending or creasing. The lightweight chipboard construction keeps postage and carrier surcharges lower than padded or corrugated mailer alternatives, making this format practical for high-volume programs.
Each case contains 100 mailers. The kraft finish presents a clean, professional appearance compatible with both branded and unbranded shipping applications. Cases ship via parcel carrier, supporting consistent inventory replenishment without requiring freight coordination.
