Making multi-layer transparent packaging sustainable
Manufacturing companies across the globe are seeking ways to reduce waste in their processes. This not only helps reduce costs and make their processes more efficient, but also ensures proper sustainable business practices.
Our customer works with multi-layer plastic film for food packaging. They were looking for a way to reuse scraps from their production processes and reduce their plastic waste. This waste comes from different types of multi-layer plastics which are discarded at various points in their processes. It includes polyethene (PE) and polyamide (PA) which cannot simply be put into the melting pot and be reused without losing its transparency and thermoforming properties. In food applications, consumers demand transparent food coverings.
Our innovative approach
We were able to supply a compatibilizer which improved recycling properties of food-grade films containing ethylene vinyl alcohol (EVOH) or polyamide (PA). The recycled material can now be added to a transparent polyethylene (PE) or polypropylene (PP) layer in a new multilayer structure. The resulting film is suitable for use in food applications.
