Keywords: Medical packaging integrity, leak testing, bubble method, vacuum method, ASTM standards. Medical devices rely on sterile packaging to ensure patient safety. Leakage can compromise sterility, so manufacturers rigorously test package integrity. This article explores two key methods for leak detection: the bubble method and the vacuum method. The bubble method (ASTM F2096) works by pressurizing the sealed package underwater. If leaks exist, escaping air forms a stream of bubbles, revealing the breach. This method is versatile, handling various package shapes and sizes. However, pressure control is critical. Too little pressure might miss leaks, while too much can damage the packaging or create misleading bubble patterns for porous materials. The key is to find the right balance, starting with a quick initial pressure increase followed by a slower, controlled rise until a steady stream of bubbles appears.
