The project focusses on the development of cellulose films provided with barrier functionality against gasses, humidity, grease and providing seal-ability, produced in a total new way. There are many plastics like e.g. BOPP with partial or full barrier performance, which are used as packaging material in the food industry. It is generally known that plastics are under pressure in relation to the public opinion related to issues like the plastic soup or the use of fossil sources and because of upcoming regulations like the Single Use of Plastics.
