Abstract
In a method for reprocessing film waste material, the film waste material is comminuted into recycling material by means of a comminuting device. The recycling material is fed by means of a feeding device in a multi-shaft screw machine. In the multi-shaft screw machine, the recycling material is plasticized into a material melt and processed into raw material. The raw material may again be fed to a production installation for the production of films.
