dc.description.abstractThis dissertation addresses packaging quality defects of 4-5% that are observed at SAH SPA LILAS Algeria, specifically in the MPM paper tissue line. This research identifies and classifies defects using the Ishikawa (fishbone) analysis method. The research collects causes systematically based on the 5Ms: Machine, Method, Man, Material, Environment. Key findings include machinery that was extremely old with installation from 2012 and little maintenance, methods not following business standards, employees that were poorly trained, materials of variable control, and contamination from the environment related directly to packaging quality problems. The research presents short-term actions (a calibrated conveyor belt, electrostatic control techniques, prevention of dust) and long-term actions (equipment upgrading, preventive maintenance techniques, standard operating procedures, proper employee training). All recommendations outlined in this dissertation were set to mitigate and enhance packaging quality and uniformity, increase the reliability of machines, reduce waste generation, increase operational efficiency and ultimately quality of product for SAH SPA LILAS as an Algerian market leader.
