Tamper Evident envelopes offer the ultimate level of security and confidentiality featuring a special security peel ‘n’ seal strip. Once a sealed envelope is opened and the tamper-evident seal broken, the word ‘OPENED’ appears in the flap window, letting the receiver know that the envelope has been opened and confidentiality lost. The tamper evident seal is a deterrent to ensure mail confidentiality. They are available in various designs and sizes, all featuring peel ‘n’ seal security strips.
