Invisible product protection in the form of marking substances offers good counterfeit protection and thus effectively prevents brand piracy. The demand for invisible marking and the corresponding testing technology for different end applications in plastics processing is constantly increasing.

Grafe Advanced Polymers GmbH, Blankenhain/Germany, has developed a simple and safe solution. The basis is special markers: The highly complex pigments with special physical properties designed for this purpose are used in minute quantities within the plastic matrix. With an appropriately calibrated detector, products equipped with them can thus be read and authenticated. At the same time no changes in properties can usually be observed.

This addition can be added as a combi-batch, i.e. as a masterbatch in combination with a color, or as a special marking batch without color. The detectors can use an LED display to check within seconds whether the unique marker is contained in the product and whether this item is the original product. In general, there are 2 options: x-ray and light fluorescence. With the first option, the base color has no influence (not even black). The advantage here is low addition dosage and batch price, but this method requires higher investment.
