Waste reduction, Recycling, lightweighting and renewable materials - these are the buzzwords around reducing the CO2 footprint of packages. Solutions –at least partial ones - exist for all these approaches now. A challenging subject is certainly the recycling of multilayer structures as unlike components of multilayer structures cannot be easily recycled into film or non-film applications. We have been developing a variety of compatibilisers and modifying agents in order to facilitate the recycling of multilayer structures. Our additives can compatibilise unlike materials such as PA and PE or polyolefines and EVOH and thus reduce the gel level making the recyclate suitable for recycling back into the film. We are also working on new compatibilisers that allow the recycling of unlike materials such as PE and PP: The importance is however, in order to contribute a maximum to the success of in-house recycling to design the package for recyclability and to eliminate as much as possible material combinations that represent a barrier for recycling
