WEB EXCLUSIVE: Two companies recently announced developments in high-security anti-counterfeit “taggant” additives that can be compounded into plastics. A new series of taggants has been launched by Sachtleben Chemie of Germany (U.S. office in White Plains, N.Y.), a major producer of titanium dioxide pigments as well as barium sulfate and zinc-based functional additives. The security particles are detectable only using special analytical procedures and can be incorporated directly into plastics products through direct compounding or via masterbatches. The particles are said to be approved for use in contact with foodstuffs (including Kosher and Halal foods).
In addition, an existing supplier of such taggants, Microtrace, LLC of Minneapolis, announced recent enhancements to its Microtaggant technology as well as several ready-to-use solutions for product security and brand protection. The enhancements are said to make this “the most robust traceable, anti-counterfeit technology available.” The taggants are uniquely encoded for each customer. In its most basic form, the Microtaggant is a unique numeric code sequence in a multi-colored layer format. In more complex form, it provides multiple layers of security through incorporation of several nano-taggant technologies in a single microscopic particle. Verification and detection is done with a variety of inexpensive hand-held readers and scanners. The taggants are available in dry particle form for compounding or as a finished masterbatch. The taggants can be used in a variety of plastic resins and colors, with no change in processing conditions.
