Security envelope with closing system of two VOID security tapes, one green and one red, and a very high adhesion glue. The same denounces the word manual opening and through the application of gas and/or heat sources, with the flap showing the word VIOLATED under the flap. It is also possible to apply sequential numbers, both on the flap and on the body of the envelope, in order to prevent a fraud attempt. This level of security is indicated for use in value carriers; however, it can be applied in any other type of segment that requires a high level of security.
