Things to Consider Before Buying The Best Security Envelopes

The security envelope is a necessity for retailers, companies, and other organizations that handle sensitive information. You can keep your personal data safe from prying eyes who might otherwise intercept your mail. In addition to patterned tints and VOID watermarks, there are other options available for security envelopes.

Here are a few things to consider before you buy security envelopes:


Various sizes and shapes of security envelopes are available, ranging from small coin envelopes to large boxes that can be used to send items such as plates and DVDs. For letters, you’ll want an envelope that fits both an 8 1/2-by-11-inch piece of paper and a regular No. 10 envelope.

Window or no window

Choosing whether to have a window in your security envelope is up to you. A window isn’t necessary in some cases; for example, if you’re sending documents regarding an upcoming job interview, it’s best not to have one

Security features

When looking for security envelopes, this is one of the most important features to consider. Make sure that your mail cannot be easily accessed through the envelope. You should consider a tamper-proof seal as the number one feature for document protection. Through this seal, the recipient will know whether anyone has accessed their mail or not when they try to open the envelope.

Security tint

Another great feature of a security tint is the ability to see if anyone has attempted to open your mail. The security tint will be visible if your mail has been tampered with when held up to a light source. Additionally, make sure that your mail is secure.


Heavy-duty envelopes may be more durable than light-duty ones, but they may not be as protective. As the envelope weighs more, the likelihood of it tearing increases.

Final Words

Finding the best security envelopes isn’t always easy. There are many different options available and each manufacturer has a different range of materials, sizes, and prices. Choosing from among them can be a difficult process. Hopefully, the information we have provided has made things easier for you by guiding you through some of those choices.
