They are indispensable in modern everyday life: Flexible packaging made from several layers of film enables the hygienic and safe storage of many foods. However, the versatile packaging has a problem: sustainable disposal. After use, the bonded films in the material mix are difficult to separate from one another - and that is why such flexible packaging is unfortunately only partially recyclable.
Covestro has identified the problem - and has developed a process for recycling companies and packaging manufacturers to address this problem: In the case of multi-layer film packages laminated with polyurethane (PU) adhesive, the respective materials can be separated from one another again thanks to the new technology. The team will now present the development at the K 2022 trade fair from 19 to 26 October in Düsseldorf.
