sustainable nature of SABIC’s mass balance certified renewable polymer from second-genera- tion feedstock, the exceptional printability, die- cutting, anti-static and non-stick properties of these films deliver maximum value throughout the entire life cycle of the labelled products, including end-of-life recycling.” The BOPP label film is supplied to Karydakis, a specialist in optimised printing techniques, ink formulations and conversion technologies tailored to PP-based IML. Cut to shape for stacking, the IML labels are supplied to food packaging moulder Kotronis which uses them in the production of cups and tubs. Giorgos Karydakis, General Manager at Karyda-


kis, says: “With this collaborative initiative, we are demonstrating the feasibility of bio-based materials in the production of high-quality IML labels. We offer our customers a wide range of attractive printing options for cups, tubs, jars, shakers and pails in sizes from 50 ml to 50 l, including addition- al digital watermarking with material information in line with the European HolyGrail 2.0 initiative for smart automated mechanical recycling.” IMD foils specialist Leonhard Kurz has turned its


product development towards sustainable materi- als. At Fakuma 2023, one demonstration involves injection moulding a clothes peg made entirely from Recopound, a post-industrial recycled plastic. It claims to be the first company to produce a high-quality recycled PET compound from produc- tion residues from the graphics industry. Kurz recovers waste PET transfer carrier foils from its customers and reprocesses them into Reco- pound granules in a specially developed procedure that is optimised for injection moulding. The recycled compound can be decorated to a high standard and used for stable and robust products. The company says that the clothes peg moulded

of mould maker Deckerform using a manual hot-stamping machine from the Kurz subsidiary Baier and given away to visitors. Kurz will also show other Recopound applications including a watering can, a flowerpot, and a stable transport and storage box. It is also teaming up with Deckerform at Fakuma for the production and finishing of a door trim strip made from post-industrial recycled materials from the Nuremberg-based company Sysplast. Kurz says: “A special manufacturing process is used here, namely thermoplastic spray foaming. This process guarantees high stability of the component and at the same time uses less material than conventional injection moulding. Another plus is that due to the foaming, the weight of the door strip can be reduced by approximately 10 to 15%.” At Fakuma 2023, Pröll will be showing new


products in its range of ink systems and protective lacquers for IMD/Film Insert Moulding (FIM) technology. These technologies have been expand- ing into functional applications, including the growth area of printed circuitry. Pröll’s Noriphan HTR N is an established, formable, back-mouldable and solvent- based one-component screen printing ink for FIM. A new addition is the deep black opaque Noriphan HTR N 990/011 NC, which is non-conductive black for printed electronic applications. This colour shade does not contain carbon black, has a high optical density, an electrical resistance in the giga ohm range and is radar transmissible. Pröll says it can be used for decorative prints but is mainly used for plane multi-layer printing or
