identification codes can include any information, such as manufacturer, batch number or production date, so that materials can be traced back to their origin. Technical properties of the Poltag molecules can be adjusted and adapted to ensure maximum stability and compatibility with the target product and its specific application. They are designed and synthesised individually for each customer by Polysecure, which ensures a particularly high level of protection against counterfeiting and manipulation. Poltags are thermally stable up to 380°C, chemically stable through resistance, for example, to UV radiation, acidic and basic solutions and organic solvents, as well as being mechanically stable. These robust properties, together with the anchoring of the Poltags directly in the material, means they can be preserved and detected for many years. Poltags can be homogeneously processed in solids (for example, thermoplastics and duroplas- tics) and liquids, such as organic solutions, fuels and water-based liquids. Poltag macromolecules are identified by tandem mass spectroscopy (MS/MS). Only a few 100mg of labelled material is required for precise detection, which in polymers is around 1ppm. The quantita- tive nature of mass spectroscopy means detection of Poltags can also be used to monitor and measure the concentration of marked materials in an end product, such as recyclate content. Moesslein says that Polysecure has received legal confirmation that its Brandproof mobile pocket detector technology is now accepted in German courts for authentication of products. In future, the company says that it will also provide its PFP identification software via a secure internet database so that customers can link the individual hash codes with their DPP databases.
Taggant integration Avient has developed its Plastiward counterfeiting technology to provide protection for plastic articles in multiple applications. Offering fake checking in real-time, the company says Plastiward brings counterfeiting protection of plastic articles close to the end consumer by integrating taggants into a product using a polymer masterbatch. It describes it as a fully integrated turnkey solution that allows an enforcement team to take swift action against fraud.
Plastiward combines Avient’s polymer modifica-
tion expertise with the in brand protection tech- nologies developed by banknote security ink specialist Sicpa. It uses proprietary taggants integrated directly within the polymer together with a handheld detector to offer instant fake checking in the field. A secure monitoring platform running on a smartphone or tablet captures field inspection data, which is transmitted in real-time. BASF Venture Capital (BVC) recently made a
strategic investment in Oceanworks, a sustainable plastic solutions provider that aims to deliver traceability and transparency to recycled plastics through digitalisation. Based in the US, Oceanworks offers a platform for brands looking to reliably secure high-quality sources of ocean, ocean-bound, and averted post-consumer recycled (PCR) plastics. Its offering to clients includes digitised blockchain- based traceability, material quality assurance, global logistics and marketing support.
