TAMPER EVIDENT ENVELOPE CLOSURE SYSTEM

摘要

A tamper-evident envelope with a closure system that cannot be breached (without the breach becoming apparent) is provided. A mechanical component is supplied, as opposed to mere printing applied to the envelope film. An adhesive band with a release tape strip, the use of hot-melt adhesive, and the configuration of the cover flap and other envelope components ensure that tampering will be immediately evident.
