34 Extrusion International 5/2021 FILM EXTRUSION Mono-Material Films – Solutions for a Circular Economy Packaging Design for High-Quality Recycling Streams Therefore, companies along the en- tire value chain of the packaging in- dustry put their focus on mono-ma- terial structures, which will be able to substitute multi-material fi lms and laminates. These mono-solutions en- able the way to a circular economy because they are ideal for the use in new applications since they guaran- BOPET, a new opportunity is opening up with BOPE. BOPP fi lms: Great potential for high value second life products PP (polypropylene) is a very com- mon type of plastic and has many uses in products we use every single day. Bene fi ts are a good chemical tee good sortability in waste separa- tion and high-grade recycling mate- rial quality. Brückner Maschinenbau has devel- oped mono-material packaging solu- tions to close the life cycle of plastic packaging as requested by brand owners and legislations. Besides the state-of- the-art materials BOPP and Today, many packaging structures use composite structures made of various fi lms and various materials. These laminates ideally combine the required properties such as high barrier, sealability, thermal stability, puncture resistance, printability and many more. Unfortunately these multi-material structures cannot be sorted to a certain recycling fraction and are dif fi cult or even not all to recycle
