9 x 11 1/2 Mailers

Flat materials stay better supported when shipped in JAM Paper 9 x 11 1/2 inch photo mailers. Rigid paperboard construction helps protect photographs, certificates, artwork, promotional pieces, and important documents from bending during handling. The dimensions provide useful space for professional prints and paper goods while maintaining a compact mailing profile.

White and brown kraft finishes offer versatile choices for business correspondence, creative projects, and customer deliveries. Sturdy construction reinforces the contents, while peel & seal closures allow packages to be secured quickly without separate adhesive. These protective envelopes suit studios, offices, retailers, and organizations mailing valuable flat pieces.

Client proofs, presentation materials, certificates, and finished artwork often require more structure than a standard paper envelope provides. This mailer size works well for recurring professional shipments as well as occasional personal mailings. A firm exterior helps keep printed contents organized and presentable from packing through delivery.
