13 x 18 Mailers

Oversized prints and documents often need firm packaging that helps preserve their shape throughout mailing. JAM Paper 13 x 18 inch photo mailers provide rigid support for photographs, artwork, certificates, presentations, marketing pieces, and other broad paper-based contents. The generous dimensions allow larger materials to remain flat rather than folded for shipment.

Classic white and natural brown kraft finishes provide versatile choices for professional correspondence and creative deliveries. Sturdy paperboard construction helps limit bending during handling, while peel & seal closures simplify preparation for outgoing packages. These rigid mailing envelopes work well for photography orders, client materials, portfolios, and business documents.

Creative studios, offices, schools, and retailers can use this larger size when standard document envelopes do not provide enough surface area. Artwork, promotional sheets, photographs, certificates, and printed projects benefit from a structured enclosure that keeps contents organized. The broad profile offers practical protection for both recurring commercial shipments and important personal mailings.
