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.
In the process, a special separation agent, consisting of natural ingredients and water, specifically weakens the bond strength of the PU adhesive. Laminated films in multilayer packaging can be separated after use. The individual materials can be recycled later.
At the K 2022 trade fair, the team presented the technology to the plastics industry for the first time and is looking for potential partners from the packaging and recycling industry to further develop the process together with them.
