The feasibility of using a non‐destructive ultrasonic technique for detecting defective seals was studied. It was found that ultrasonic velocity could be used to distinguish defective seals (containing wrinkles, voids, minute amounts of carrot, beef pieces, moisture or bentonite as contaminants) from a good seal. Also, there was a systematic correlation between ultrasonic velocity and the levels of contaminant.
