constantia flexibles has developed constantia teos, a new tamperevident opening system for packages containing medical devices. the system was originally designed for syringes housing tumor necrosis factor inhibitors, also called tnf blockers. it is a tamperevident peelable cover foil that is functionally destroyed during initial opening and provides reliable protection against the package&rsquos illegal reuse. this lid can incorporate a variety of optional overt and covert features that further assist with tamper evidence. possibilities include holograms, customized security foil, special security pigments and inks, and uniquetoproduct security printing, such as microtext, hidden graphics, and builtin pattern deviations.
