The invention provides a leak detection system for filled and sealed pliable containers. The system comprises a continuous squeezing conveyor, a line conveyor and high and low fill level container content detectors located at predetermined positions. The squeezing conveyor moves a stream of containers while placing a predetermined pressure on the containers through a predetermined distance. The line conveyor is disposed adjacent the outlet end of the squeezing conveyor. The line conveyor is synchronized for receiving and transporting the container stream. The high fill level detector is disposed adjacent the squeezing conveyor outlet end. The low fill level detector is disposed adjacent the line conveyor at a predetermined distance downstream the squeezing conveyor outlet end.
