9 x 12 Mailers

JAM Paper 9 x 12 inch mailers accommodate documents, photos, marketing materials, merchandise, catalogs, and business correspondence without folding many standard sheets. The collection spans cushioned, flexible, and tear-resistant constructions for different levels of protection. This familiar size works across offices, retail fulfillment, direct mail, and e-commerce shipping.

Contents determine which material provides the best fit for each shipment. Bubble mailers add cushioning for more delicate goods, poly envelopes provide flexible coverage for non-fragile items, and Tyvek® options combine low bulk with strong tear resistance. Peel & seal closures across many selections also support efficient preparation for recurring business mailings.

From promotional packets and paperwork to apparel, samples, and customer orders, this size adapts to a broad range of shipping tasks. Different colors, opening styles, and constructions allow companies to choose packaging according to content, presentation, and handling needs. The assortment makes 9 x 12 mailers a useful staple for mailrooms, warehouses, retailers, and professional offices.
