The White Self-Seal Stayflats Plus® Mailer is a rigid, lightweight mailing envelope built from chipboard construction that eliminates the need for separate stiffeners. The self-sealing peel-and-seal strip creates a secure bond without moisture activation, and a pull-tab tear strip on the recipient end allows for clean, damage-free opening.

These mailers are well-suited for e-commerce retailers, photo labs, print distributors, and corporate mail rooms shipping documents, certificates, photographs, artwork, and other flat media that cannot be folded or bent in transit. The white exterior supports both branded and unbranded shipping presentations.

Dimensions measure 9 3/4 x 12 1/4 inches. The lightweight chipboard construction helps manage dimensional weight costs on parcel shipments. Sold in cases of 100; ships via parcel carrier.
