Temperature rise or slow down the temperature gradually slowed down, reducing the amount of overshoot. The same requirements apply for temperature control in bagging systems. Traditional bag making machine system is the use of digital control system to control the temperature of the film bonding bag hot knife, although the temperature control method is more accurate, but because each hot knife should be equipped with a digital display
