Schreiner MediPharm has developed specialty pharma labels with void effects that prevent illegal re-labeling, aimed at stopping counterfeiters detaching labels from empty original containers and using them again on faked products. The labels also protect variable printed data, such as expiration dates, from tampering.  

        When detaching the label, a previously hidden text or pattern irreversibly emerges. Consequently, the label can no longer be used and is thus protected from tampering. The void effects reliably indicate the re-utilization of previously used containers or alterations of subsequently added information. 

        Void effects can be integrated into existing marking labels and designs. They provide easy and effective protection against tampering with which pharma manufacturers can safeguard their products from misuse and patients from inferior drugs inside original packaging.
