Seal and Leak Testing of Cosmetic PackagesSeal and leak testing of cosmetic packages is to test the integrated performance to avoid external migration into the packages and content leakage.
By: Shirley Wu 1.Underwater Decompression MethodTake 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. 2.Positive Pressure Testing methodTake 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.
