The PrintCYC initiative consists of the recycling process of plastic, labels and printed films through various companies such as machine suppliers Brückner Maschinenbau , Kiefel and PackSys Global. Also participating are the CPP film specialist Profol, the ink manufacturer hubergroup, the converter Constantia Flexibles and the recycling technology specialist Erema. The initiative is coordinated by Annett Kaeding-Koppers as an independent packaging and sustainability consultant. The project group has achieved notable results regarding the recycling of printed plastic films and the processing of recycled material.
The need for circular economy solutions for plastic packaging requires the packaging industry to take an active role in ensuring circularity from design, following the entire life cycle. Project members joined forces to research and test new ways to create circular economy solutions based on post-industrial waste from printed plastic films in Telegram Database the most cost-effective way. However, deinking technology was not considered within this project. plastic recycling In phase 1 of the plastic recycling process project, PP packaging and film samples containing >50% PP recycling could be successfully produced. The base material was printed on biaxially oriented PP (BOPP) films on nitrocellulose (NC)-based ink formulations.
However, the quality of recycling was not completely satisfactory with respect to material properties such as color, odor, and processability. Printed Film Waste Based on these early promising Phase 1 results, PrintCYC members strived to improve further by testing alternative ink formulations for printing on BOPP and low-density polyethylene (LDPE) films. The switch to a polyurethane (PU)-based ink system in flexographic printing in phase 2 resulted in significant improvements to the mechanical recycling process on a production line typically used to reprocess waste materials from printed films in the practice. Due to the high temperature resistance of the inksno volatile by-products, odor or gels were observed.
