  • Mailing: Sized perfectly to fit standard paper without creasing or folding it, these envelopes are the best option for sending documents or paper items that must be adequately protected during transit.
  • Storage: Use 9 x 12 envelopes to store letter-size paperwork, custom brochures, reports, certificates or even catalogs. They provide an extra level of protection while sorting or moving papers, thereby decreasing the number of folds or creases.

Closure Type

The best closure type for your 9 x 12 envelopes depends on whether you primarily want to mail or simply store them.To mail your items securely, it would make more sense to select a self-seal, gummed or glue closure type so that your papers won’t fall out or be tampered with during transit.

Envelope Window

To simplify the mailing process, you may want to choose a 9 x 12 envelope with a window feature. These windows allow you to print the recipient's address on the paper contained within, which keeps from having to write out each individual recipient address.You can choose a security-tinted window so that it’s more difficult to infringe on your recipient’s privacy during the mailing process.
