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. The lightweight chipboard construction helps manage postage costs at scale. Cases ship via parcel carrier.
