The same lid for every pot
Plastic is a bundle of materials with many economic and ecological advantages and is often used for food packaging. To increase the recycling rates optimal sorting and recycling processes are required. In the food industry heat seal coatings often play an important role for packaging which come with heat sealable lid structures. Those are often composed of different plastics, increasing the difficulty of the recycling process.
Since it is difficult or not even possible at all to mechanically recycle composite materials consisting of multi-layer films heat seal coatings should be considered when designing a sustainable food packaging. Simply designed mono material packaging is the key to avoid incineration of hard to recycle packaging.
