The White Self-Seal Stayflats Plus® Mailer delivers large-format flat protection through lightweight chipboard construction that keeps contents rigid without additional stiffeners or inserts. The peel-and-seal closure forms a secure bond without tape, and a pull-tab tear strip allows recipients to open the mailer cleanly without tools.
These mailers are well suited for print fulfillment, art and photography studios, architectural and engineering firms, and e-commerce operations shipping posters, drawings, proofs, certificates, or any oversized flat material that cannot be folded or rolled. The white exterior provides a clean, professional presentation at the point of delivery.
Each case contains 50 mailers. The lightweight chipboard construction helps minimize per-package weight, which can reduce carrier costs at volume.
