Abstract: A packaging material processing machine (10) is described. It comprises an upper processing tool (12) and a lower processing tool (14) being configured for interacting with each other in order to process the sheet material. Moreover, a drive unit (18) is provided which comprises an electric machine (20) and a flywheel (22). An electrical supply unit (28) is electrically connected to the electric machine (20) such that the electric machine (20) is operable as an electric motor. Moreover, an electrical energy recovery unit (44) is electrically connected to the electric machine (20) such that the energy recovery unit (44) is able to store or transfer electrical 10 energy provided by the electric machine (20) operating as an electric generator, the flywheel (22) being rigidly connected to the drive unit (18). Additionally, a method for operating a packaging material processing machine (10) is presented.
