Cosmetic package leak testing is to test integrated performance to avoid external migration into package & content leakage. Commonly used testing methods are as follows

• Underwater Decompression Method: Take Labthink MFY-01 Leak Tester as example, this leak tester is made according to underwater decompression method. Testing procedure is: put proper amount of distilled water in vacuum chamber, and immerge specimen completely into the chamber. Set vacuum pressure and time, start test. Tester will begin vacuumizing the chamber to form inner-out pressure difference for immerged specimen. Observe gas leakage of the specimen and determine sealablity of the specimen.
• Positive Pressure Testing method: Take Labthink LSSD-01 Leak and Seal Strength Detector as example. This tester applies positive pressure testing method. Through pressure exertion into inner package to test compression resistance, sealing performance and leak index so as to achieve integration and seal strength testing.
