ABSTRACT:
In a continuous motion hot air sealer the amount of heat applied to the area of film to be sealed is varied in accordance with the velocity of the film by programming the hot air generator in a straight line relationship between sealing temperature and film velocity as determined from data on high speed temperature and low speed temperature which will produce good heat seals.
