The napkin plastic film is a common material in napkin packaging. It is mainly made of plastic. Common plastic materials include polypropylene and polyethylene. Some printing technical solutions have also appeared in the prior art. For example, a water-based ink printing film multi-color gravure printing machine recorded in the publication number CN219650784U includes a chassis, an ink cartridge, an ink delivery roller, an ink feeding mechanism, a printing roller, a first coupling, a second coupling, a clamping mechanism, a rotating shaft, a driving motor and a pressure roller; the ink cartridge is slidably arranged in the chassis; a lifting mechanism for pushing the ink cartridge to move is arranged on the chassis; the ink feeding mechanism is arranged on the chassis, and the output end of the ink feeding mechanism is connected to the ink cartridge; the ink delivery roller is rotatably arranged in the ink cartridge; the driving motor is arranged on the chassis, and the rotating shaft is rotatably arranged on the chassis;
