8 1/2 x 12 Mailers

Letter-size materials and medium-sized products gain additional protection from an envelope with a cushioned interior. JAM Paper 8 1/2 x 12 inch bubble mailers suit documents, catalogs, samples, accessories, merchandise, and other contents that may encounter bumps during delivery. The familiar dimensions also make this size convenient for office mailrooms and e-commerce packing areas.

Material choices make it possible to select a mailing envelope based on the shipment and packing needs. Kraft paper styles offer a traditional business appearance, while poly bubble mailers provide a smooth exterior with protective interior padding. Both options combine flexible packing with a practical size for everyday commercial shipping.

Efficient closure features can make repetitive packing tasks faster and more consistent. Peel & seal designs secure outgoing packages without separate adhesive, while select kraft styles include tear strips for easier opening by the recipient. These mailing supplies work especially well for retail fulfillment, office distribution, customer purchases, and promotional sends.
