Bubble leak testing equipment

The bubble leak testing equipment is the conventional method of determining the seal integrity of packages by submerging the packages underwater. Leaks are observed by the stream of bubble rising from the location of leaks. The test are initiated by submerging the packages in the water-filled chamber and then, pressurized. This leak testing method is useful when we need to determine the exact leak locations.

While this method can be used for testing wide range of packages at the same vacuum level, it is essential to match the vacuum level to the package size to avoid over-stressing the package during testing. The preset vacuum level is determined by the maximum level of stress that is likely experienced by the package during its lifecycle, for example from factory to the supermarket shelf.
