To establish the research method for the sealing integrity of the injection bottle packaging system for human albumin injection.
For the injection bottle packaging system of human albumin injection, positive control samples with pore diameter of 1 μm were prepared using a glass micropipette, positive control samples with pore diameter of 2, 5 and 10 μm were prepared using laser drilling. Two deterministic sealing integrity testing methods, vacuum decay method and high-voltage leak detection method were developed and tested.
The vacuum decay method could not effectively detect the leakage of the packaging system for the human albumin drug preparation due to the blockage of the leakage hole. In contrast, the high voltage leak detection method effectively avoided undetected leakage caused by the blockage of the leakage hole by the liquid medicine. The test voltage was set at 9 kV, with a threshold of 15 W. Method validation demonstrated that the high voltage leak detection method exhibited good repeatability, intermediate precision, accuracy, and durability, with a leakage detection limit of 1 μm.
The high-voltage leak detection method can serve as an effective means of inspecting the sealing integrity of the injection bottle packaging system for human albumin injection. The procedure is straightforward, and the results are both accurate and reliable, while also being non-destructive to the packaging. This method is well-suited for the sealing integrity inspection of commercial product packaging systems.
