Stayflats Plus® Mailers in the 20 x 27 inch size are built from .028 kraft chipboard thick enough to maintain rigidity without inserted stiffeners. The self-seal peel-and-seal strip secures the closure without tape, and a pull-tab tear strip lets recipients open the mailer cleanly without tearing into contents.
The rigid chipboard construction makes these mailers a reliable choice for print distributors, photographers, galleries, and retailers shipping posters, large-format artwork, architectural drawings, and oversized marketing materials that cannot arrive creased or rolled. Fulfillment operations processing high volumes of flat goods benefit from the no-prep closure that requires no additional materials at the packing station.
Each case contains 50 mailers. Interior dimensions measure 20 x 27 inches, and the lightweight chipboard construction helps manage postage costs at scale. Cases ship via parcel carrier.
