The general Impulse Sealer has a problem of sealing quality because continuously sealing process results in an undesirable temperature rise, which may accumulate the heat during the operation. In order to address such a drawback, the controlled sealing temperature method can be effectively utilized compared with the general controlled time method. As such, a temperature sensor with capability of detecting the sealing temperature was installed, and a separate PCB was manufactured to control the sealing temperature by measuring and calculating the detected temperature. The temperature changes during the temperature rise and maximum temperature after continuously operation were investigated using an Impulse Sealer system. Next, the results obtained from experiment were compared with each other. As such, the maximum temperature was 70.3oC, whereas 8.9oC was recorded as control temperature. It implies that this controlled temperature system prevented the undesirable temperature rise, thereby causing a consistent sealing quality.
