MULTI-LAYER PACKAGING | MATERIALS
Polymer recycling experts from Fraunhofer Institute for Process Engineering and Packaging (IVV) worked with Lömi – a plant constructor – to develop a demonstration plant for the solvent- based CreaSolv recycling process. This was used to make recycled material prototypes from LDPE, PP, PA and PET. These were tested for film and fibre applications. The project, which ended in April, managed to
recycle plastics from post-consumer multi-layer packaging and fibre-reinforced car parts – for use in packaging and automotive applications. In one example, researchers recovered polyamide from post-industrial scrap. It was extruded into cast film and biaxially oriented. The project organisers say this is the first demonstration of an oriented PA film with such a substantial recyclate content (30%). The material has been converted into a multi-layer structure and prototype product – a stand-up pouch for liquid filling. Fraunhofer IVV researchers also worked with film manufacturer Amcor to develop mono- and multi-layer films – containing recyclates – for packaging of wipes and cosmetics. “The positive results of the recycling and
application tests are based on our expertise and close collaboration with industry partners,” said Martin Schlummer, deputy head of the department of process development for polymer recycling. “We are looking forward to commercialising CreaSolv technology soon.”
Recycling PE/PA BASF presented detail on PE/PA recycling at last year’s Multilayer Flexible Packaging conference, organised by AMI. Rolf-Egbert Gruetzner, senior manager technical
support extrusion polyamides at BASF, told delegates that polyamide offers several advantages – including downgauging and better barrier properties – to multi-layer packaging. “It does not make any sense to sacrifice these advantages for the sake of a ‘mechanical-recycling only’ approach,” he said. He said the use of compatibilisers – for blends containing more than 30% PA – could be incorpo- rated into the original multi-layer film, during regranulation, or by adding it during final process- ing of the recycled film. “While PE/PA6 films need a regranulation
Optimize the presentation & creation of food packaging Consumers
Fogging most commonly occurs when there is a temperature difference. It can disturb the appearance of packed food. Van Meeuwen can assist you in creating clear sheet which is less sensitive for fogging. It will satisfy your customers and consumers.
Production process Too much friction of the plastic sheet can lead to process failures and loss of quality. Anti-blocking agents reduce this friction, making it easy to separate packages from each other. It also ensures that exactly one cup or tray is picked up at automated filling lines.
