Schreiner MediPharm has introduced a counterfeit and tampering protection solution whose void effect makes it exceedingly difficult for counterfeiters to successfully reuse original packaging. The company’s tailored Void-Labels make previously covert messages readily visible upon peeling, making a package’s first opening clearly and irreversibly apparent.
 
According to the company, counterfeit medicines worldwide amount to a roughly $200 billion black market that, each year, is growing by an untenable 20% – twice as fast as the legal medicines market. 

In February 2019, the European Union responded to the growing counterfeit medicines market by issuing the EU Falsified Medicines Directive for pharmaceutical packaging. The global ISO 21976 standard also states how security features can be used on pharmaceutical packaging and how tampering attempts can be verified. In addition, it specifies requirements for protecting the authenticity of pharmaceutical packaging. The tailored Void-Labels from Schreiner MediPharm aim to satisfy these requirements.  

By revealing a hidden first opening message once the label is peeled, Schreiner MediPharm’s Void-Labels make it nearly impossible for counterfeiters to successfully reuse original packaging. Suitable not only for cardboard boxes, but also for glass and plastic containers, the solutions are individually tailored. Following extensive tests, Schreiner MediPharm adapts the closure seals specifically to the relevant packaging, material, substrate and application. Seals also can be custom designed, offering film material choices in various colors as well as white and transparent. Depending on the intended goal, various void effects can be accomplished, including: 
 
•          No Transfer: Peeling off the label leaves no residues on the pharmaceutical packaging. The void effect becomes visible only in the label after it has been opened for the first time. Reclosure of the label with the visible void effect is possible. 

•          Semi Transfer: Peeling off the label leaves partial residues on the pharmaceutical packaging. After first opening, the void effect is visible both in the label and on the packaging. Reclosure of the label with the visible void effect is possible. 

•          Full Transfer: Peeling off the Void-Label leaves a complete coating layer on the packaging. Consequently, the void effect is visible on the pharmaceutical packaging and in the label after first opening, but reclosure of the label is not possible. 
 
In addition, a convenient tab can be integrated for easy handling by final users. Due to the addition of overt or covert authentication features, the Void-Labels can also provide proof of authenticity. Schreiner MediPharm aims to ensure optimal and reliable performance of the seal that is adapted precisely to the respective packaging and specific threat scenario.
