What Are Window Envelopes?

A window envelope is a type of conventional envelope that features a plastic film, or window, to allow the recipient’s name and address to be printed on the document or paper within. These envelopes are typically purchased alongside other shipping, packing & mailing supplies.

They are ideal for businesses and corporations because a typed name and address look more professional than handwriting. These window envelopes pair great with other mailing supplies, such as envelope moisteners and letter openers for keeping paperwork and documentation organized and labeled.

What Types of Envelopes with Windows Are Available?

Window envelopes, also called commercial envelopes, have triangular flaps and are sized according to number. The most prominent are numbers 7, 10, 12, and 14. Envelopes with windows can range in size from about 3.75 x 6.5 inches to 5.5 x 11 inches. Each one typically features a blank field for handwritten or printed mailing and return addresses, or for address imprints with pad-and-ink custom stamps. Further information on how to pick the right size envelope can be found on the Quill business envelope size chart.

Some have single or double windows to display pre-printed addresses on inside documents. For businesses who often mail out sensitive papers with confidential information, some business window envelopes include tinted inner weaves to conceal the contents when held against a light. Like many conventional envelopes, business envelopes for outgoing mail with windows have secure closures, including moisture-activated adhesives and peel-and-seal strips.

How Can Business Envelopes with Windows Be Used?

Whether you work at a law office or run your own medical practice, window envelopes can be used for an array of applications across different businesses and industries. They can safely transport documents and sensitive materials and elevate the appearance of any greeting or invitation. Here are just a few things you can send with window envelopes:

  • Interoffice communication: Interoffice business window envelopes feature a button and string design and are sized to fit standard letter sized sheets of paper, making them ideal for transferring and tracking documents between different departments within the same company.
  • Legal and medical documentation: Tear and moisture-resistant open window envelopes, like the ones created by Tyvek, are ideal for sending out medical records and legal paperwork that can’t afford to be damaged or destroyed.
  • Letters and invoices: Number 10 window envelopes are the most common size available, measuring 4.125 x 9.5 inches, and are perfect for mailing out most forms of business correspondence, such as letters and invoices.
