To meet the growing tamper- and counterfeit protection demands made on security features for products and packaging, Schreiner ProSecure integrates its new invisible FluxSecure authentication technology into self-adhesive products. The FluxSecure feature can be quickly checked even through product enclosures and packaging. In addition, it is easy to integrate and ensures reliable authentication.

The FluxSecure technology by Schreiner ProSecure consists of a magnetically encoded, extremely thin thread which is inserted between the adhesive and the masking paper. FluxSecure has a diameter of about 30 micrometers, which makes it thinner than a human hair. The delicate thread consists of a metal alloy mixture and is surrounded by a glass coating. The magnetic properties of the security feature are read out without line of sight, using a handheld reader or a sensor that generates a magnetic field. This allows products to be verified even through heavy and metallic packaging. The readers are specifically adapted to the customer’s system solution.

Authentication is indicated by both an optical and an acoustical signal. Customized sensor solutions are available for integration into machines, equipment or products or for stationary reading systems. The magnetic properties can be modified through variations of the alloy and changes to the thickness and length of the FluxSecure thread.

In addition, the alloy mixtures are customized and therefore not reproducible. The FluxSecure technology can be easily integrated into existing products like folding boxes or blister packs and marking solutions. Since the security feature is hidden, it does not interfere with specified design patterns. Combinations with additional overt or covert security features are possible as well.

The FluxSecure technology not only provides brand owners with an efficient method to authenticate their original products, but to automate machine calibration and settings and to introduce further customer service tools.
