A windowed envelope features a clear plastic pane that reveals a portion of the document inside. This allows senders to create and send information or personalized mail to individuals. By adding windowed envelopes to your supplies your recipients can easily understand what the vessel contains and who it is intended for.

What Can a Windowed Envelope Be Used For?

Windowed envelopes can be used for storing or mailing important documents, catalogs, pamphlets, holiday cards and much more. The avid organizer will use them to store pens, paper clips, thumbtacks and other small office supplies. Due to the quality paper and other materials, window envelopes are perfect additions for business and personal mailings as well as organizational tasks.

What Features Should Be Considered When Buying Windowed Envelopes?

Like any envelope being used around the house or office, there are certain characteristics to think about depending on the use or need. Some variables to consider when looking for a windowed envelope are:

  • Size - Ensure that the contents being held within are properly secure and will fit.
  • Flap style - Buyers can choose between a square-shaped, v-flap, open end or wallet style.
  • Color - This can be important for personal preference or branding purposes.
  • Window location - This will depend on what is being sent and where the recipient information is located on the documents.
  • Security tints - If you have confidential mail this feature can protect your documents from unauthorized viewers.

What Pack Sizes Are Window Envelopes Available In?

Staples offers envelopes with windows in various pack sizes from as few as 25 all the way up to orders of 1,000. The available quantities will vary depending on the style.

What Is a Security Tint?

A security tint darkens the window, preventing onlookers from seeing the contents inside. Using a security tint is a good practice when transporting sensitive information that shouldn’t be tampered with. Consider using a security envelope if you plan on sending checks, cash or important documents such as health or government records. Windowed envelopes are a great option for businesses and agencies that require extra security while still being able to display important details.

Are Envelopes With Windows Recyclable?

Yes, but there are a few factors to consider when recycling your windowed envelope. The paper portion of window envelopes is recyclable, however the plastic must be removed and thrown away. While paper can easily be broken down at most recycling centers, it is more difficult to degrade the plastic and only some places can do so. If you’d like to recycle the plastic, check with your local recycling center first to see if they require it to be removed.
