Food packaging, for example for frozen products, has long since become an integral part of our daily lives. Particularly in the case of frozen products, however, the end consumer repeatedly encounters plastic components in the packaging, some of which are large. However, the constantly growing appetite for frozen pizza and frozen products in general, as well as other industrially processed foods, also has a downside: so-called pizza films are used to package frozen pizza, primarily to prevent the direct contact of fatty foods with recycled cardboard and thus to protect against the contact migration of mineral oil components into the food. In addition, these films act as a water vapor barrier to protect the food from drying out or softening. As a result, frozen pizzas alone generate more than 2,500 t of plastic waste per year in Germany - and the trend is rising. The aim of the present project is to develop a novel process for coating packaging board material made from recyclable GD2 cardboard with several layers of so-called barrier coatings to prevent the migration of mineral oils from printing inks into the food. For the first time, the newly developed coating also acts as a water vapor barrier. The novel coating will therefore make film packaging obsolete while maintaining the functionality of the packaging, which will result in a significant reduction in plastic waste. The development includes: 1.) The development of application-specific, functionally optimized formulations for the barrier coatings. 2.) The development of the process for applying the novel coating. 3.) The development of a highly automated coating system that allows short changeover times as well as local application directly at the packaging production site.
