Abstract
Systems, methods, and apparatus are provided for detecting improperly sealed portions of sealed packages. For example, in one embodiment, a package leak detection system automatically provides pressure within a tank for a predetermined period of time. The tank is at least partially filled with colored fluid with a sealed package being at least partially submerged in the colored fluid. In the tank, the pressure inside the tank forces the colored fluid into improperly sealed portions of the sealed package. After the predetermined period of time has elapsed, the package leak detection system automatically shuts off the package leak detection system and releases the pressure within the tank so the sealed package can be inspected for potential leaks.
