Abstract
The integrity of a seal in packaging film is monitored during packaging of loose, free flowing product and adaptive control of the packaging method/apparatus is provided in response to the determination made. The pressure being exerted between the sealing jaws upon reaching a closed position and the seal being formed is monitored and analyzed to evaluate the seal integrity in a dedicated microprocessor. An adaptive, real time signal is provided to a CPU/controller to adjust the relative product flow and packaging film movement.
