Many people add security to their documents and then fail to
provide a secure envelope for delivery of the document. There are several options
for adding security to your envelopes. The sensitivity of the information being
sent will determine what level of security you would want to add to your envelopes.
Shown below are several options for adding security to your envelopes.

Inside Tinted Envelopes
Inside tinted envelopes are printed on the inside with a deflecting
pattern. The pattern makes it very difficult, if not impossible, to
be able to see thru the envelope and read the content within. The deflecting
pattern helps protect sensitive information from being read by someone
it is not intended for. There are standard and window envelopes available
with an inside tint but it could be added to most any type of envelope
as a custom feature.

Note: When ordering
a window envelope that is used for a check or other negotiable
documents, be sure "PAY TO THE ORDER OF" does not
show through the window. This would indicate that there was
a negotiable document enclosed. Also, be sure no other sensitive
information shows through the window opening.

Heat Sensitive Envelopes
The use of heat reactive-irreversible ink helps provide
a means of assuring that the seal of the envelope has not been tampered
with by the use of heat or steam,  protecting
against access to the envelope's content. The heat reactive ink is colorless
when printed. When it is exposed to heat between 185°F (85°C)
and 212°F (100°C), sharp color appears and does not disappear
once the temperature is lowered. This ink is only available for use
on dry offset presses.

Tamper-Evident
Envelopes
Tyvek® Tamper-Evident - The Tyvek®
envelopes have a special seal on them that indicates if the seal on
these envelopes have been broken before the recipient receives the envelope.
Once the sealed flap is opened, the words "OPENED" appear
in the window on the flap. It cannot be resealed to hide the "OPENED"
warning in the window.
Tamper-evident envelopes are used when
the envelope content is material that is confidential, sensitive or
valuable. The special seal will assure the recipient that the information
has not been tampered with since it was sealed in the envelope.
