Whether you have important documents to send, precious valuables to store or office supplies to organize, 6 x 9 envelopes are a great choice. Staples offers a variety of 6 by 9 envelopes for any size enterprise, from the humble home office all the way up to the largest corporations.

What Is a 6 x 9 Envelope?

A 6 x 9 envelope, also known as a #6 envelope, is larger than a letter sized #10 envelope. They are great options for storage, sending through the mail or organizing different areas around offices or at home.

Whether working in a business environment or organizing a home office, you’ll come to rely on 6 x 9 envelopes to mail important documents or to easily store them in an office desk or file cabinet for safekeeping.

What Can a 6 by 9 Envelope Be Used For?

While the size of 6 x 9 envelopes remains constant, Staples carries a variety of styles that allow them to be used for a range of purposes.

At Staples, we offer 6 by 9 envelopes to accommodate every business’s unique requirement. Each type offers a specialized look and use case. For example, these vessels can hold reports, pamphlets, paper clips, holiday cards and even books or magazines. Regardless of the option chosen, they are all perfect for any sized business or home.

What Pack Sizes Are 6 x 9 Envelopes Sold In?

Shop our wide variety of 6 x 9 envelopes to find modest packs of 10 envelopes, bulk purchases of 1,000 and many quantities in between.

The available packs will vary depending on the particular envelope and what other features are required. Some of these factors include:

  • Closure
  • Quantity
  • Color scheme
  • Envelope window location
  • Flap style
  • Security tint

Which Type of Closure Is Right for You?

There are many envelope closures available at Staples. The best one for you depends on your personal needs. Learn more about the differences below.

At Staples, we offer the following closure types:

  • Button and String: With these, the user wraps a string around a button to secure the envelope, adding personality to the contents inside.
  • Clasp: This sturdy metal closure is great for protecting and storing sensitive documents, and ensures your 6 x 9 envelopes can be reused. The clasp allows for an easy return to its original state for reuse.
  • Moistenable glue: The glue keeps debris like dirt or sand from entering the envelope. Because the glue strip is compact, it provides a larger area for a window.
  • Clasp and moistenable glue: Offering even more protection than the clasp or glue on their own, this durable closure option combines the clasp with durable sealant.
  • Gummed: This classic closure allows users to secure the contents of the envelope quickly and easily.
  • Open end: Similar to a gummed enclosure, open end 6 x 9 envelopes are great for providing a professional look and feel while offering a classic approach.
  • Self seal: These envelopes are a form of a gummed closure, but they allow for quicker closure by simply ripping away the sticky covering. These are helpful for sending important documents fast.
