What Can I Use a 9 x 12 Envelope For?

9 x 12 envelopes are useful for workplaces, home offices and anywhere mailing, storing or organizing documents is needed. Learn more about what 9 by 12 envelopes are good for below.

  • 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.
  • Organization: Using 9 x 12 envelopes also allows you to keep documents together in storage systems or file cabinets without stapling them or using a clip or fastener such as a paperclip, which both have the potential to damage or otherwise wrinkle the paper.

9 x 12 envelopes come in a variety of styles to protect all of your items whether you’re in the mailing process or simply organizing the office for storage. Some 9 by 12 envelopes have features that help augment your usage, such as:

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. If you’re planning on using them for storage, a durable clasp or a button and string closure will stand up better to repeated opening and closing.

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.

Color

Staples offers a variety of 9 by 12 envelope color options for your convenience such as black, blue, white, yellow, orange, green, pink and more.
