The project aims to develop novel biobased films with special barrier properties for food and packaging applications. The highlights of the project are based on its synergetic approach, whose patentability is currently being examined. The particular barrier effect of the films to be developed is to be adjusted by coupling the thermal curing of a bio-based and biodegradable barrier layer based on hybrid polymers developed at the Fraunhofer ISC with simultaneous morphology optimization (crystallite formation) in the substrate film, in one process step. In addition to the simplification of the process in terms of economic feasibility it is possible to save a lot of energy. The possibility of subsequent recycling should be favored here. By using only one type of polymer (PLA) as the main component in the substrate and a very thin barrier layer, the waste can be significantly more easily regranulated compared to multilayer films made of a wide variety of polymers. Furthermore, in a new film extrusion, under a defined amount of the recycled bio-barrier film, the components of the previously generated hybrid coating can now also be incorporated into the polymer matrix, which are to be effective there in multiple ways: - as a nucleating agent in the crystallization in the substrate film in a renewed ORMOCER coating formation. - as an additional barrier filler. - as an agent which can counteract the hydrolytic degradation of biopolymer in the renewed film extrusion due to still existing reactivities of the ORMOCER components.
