The 9 x 11-1/2" White Self-Seal Stayflats Plus® Mailers deliver rigid, stay-flat protection for items that cannot arrive bent or creased. Lightweight chipboard construction maintains structural integrity through the shipping process without requiring separate stiffeners or inserts, keeping pack weight and material cost low relative to heavier rigid mailers.
The peel-and-seal self-seal strip eliminates tape from the packing step, accelerating throughput in high-volume fulfillment centers, print shops, photography studios, and direct-mail operations. A pull-tab tear strip on the recipient end allows clean, tool-free opening without damaging enclosed contents — an important detail for customer-facing shipments.
The white exterior presents a clean, professional surface well suited to branded and unbranded shipments alike. Interior dimensions measure 11-1/2" x 9", accommodating letter-plus documents, certificates, photos, and flat printed materials. Sold in packs of 25 and parcel-friendly.
