This research studies line balancing of Pressure Sensitive Adhesive (PSA) production line. Process analysis and stopwatch time study are used to establish standard times of elementary tasks in PSA line, and elementary tasks are assigned to each worker in order that each worker has the same amount of workload. The results show that after line balancing, the number of workers is reduced from 3 to 2, the idle ratio has decreased from 38.8% to 5.5%, and the production efficiency has increased from 61.2% to 94.5%.
