Schreiner MediPharm tamper-proof Void-Labels make previously covert messages readily visible upon peeling, making a package’s first opening clearly and irreversibly apparent. 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. 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 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
