Upholding operational process stability is vital to control the quality of produced goods. Six Sigma has emerged as a prominent continuous improvement technique that supports the operational excellence of the food manufacturing sector. This case study explores the potential of tackling the leak issues in the filling-sealing operation of hot-filled paste sachet products using the Vertical Form-Fill-Seal (VFFS) machine. The DMAIC (Define, Measure, Analyse, Improve, Control) methodology was employed with other quality tools to achieve the recommended corrective measures. The results demonstrate that operational guidelines and parameters remain the crucial components to determine sealing integrity. Sigma level increases from 3.3 to 4.3 with a DPMO reduction of 27,328, significantly improving the production of good sachets. Six Sigma adoption also resulted in a declining trend of defects for the subsequent production.
