17 x 14 x 1 Mailers

Broad materials with added thickness need more capacity than a traditional flat envelope can provide. JAM Paper 17 x 14 x 1 inch photo mailers combine rigid support with a 1 inch expansion for artwork, portfolios, photographs, presentation sets, documents, and grouped printed pieces. The dimensional profile provides added space while keeping large contents neatly contained.

The combination of width and depth makes this mailing size useful for creative work that should remain flat but may contain multiple pieces. Reinforced paperboard supports the contents, and a peel & seal flap helps streamline package preparation. The white exterior maintains a clean professional look for client projects, business presentations, and important shipments.

Agencies, studios, offices, and educational organizations frequently send portfolios or presentation materials that cannot be folded into standard envelopes. Expanded photo mailers accommodate thicker sets of prints, certificates, marketing collateral, and visual projects while providing structural support. This size offers a practical alternative to bulkier parcel boxes for substantial flat contents.
