ABSTRACT:
A film sealing system and method which utilizes the combined application of pressure and high voltage static charge to achieve a high quality seal between two plastic layers of packaging material.
Pressure is applied via a sealing bar 40 to evacuate air from between two film layers to be sealed together. A static charge is then applied via a static probe 30.
Relatively high pressure air is admitted to a passage which surrounds the static probe. Such air induction of the static charge has been found to intensify the static charge penetration of the film layers and to consequently produce a higher quality film seal.
