Flexible packaging has become very popular for obvious reasons. Not only does it offer great protection, but also it is much more economical and easier to handle than rigid packaging. The market especially for packed foods is extremely competitive and does not allow for failure. On the other hand, the sustainability targets set by the brand owners are clear and require a radically new approach. Monomaterials and recycled materials can certainly help to achieve these targets. Watttron’s digital sealing technology can be retrofitted into existing machinery. Preferably we would like to see collaboration in the total supply chain with brand owners, material producers and machine constructors to address the current challenges. Regulation (EU’s Green Deal) will be a game changer, but all stakeholders should have a more proactive approach, as otherwise they might be too late when legislation about recycling targets are made mandatory.
