Sealing Performance Of Cosmetic Glass Bottles

The sealing performance of cosmetic glass bottles is crucial to its quality assurance, because the sealing performance is directly related to the protection of the active ingredients of the product, the shelf life, and the prevention of microbial contamination. The sealing performance tester can not only be used for glass bottles, but also for the sealing performance testing of flexible packaging, which is particularly important for the cosmetics industry, because flexible packaging materials are also widely used in the packaging of cosmetics.

The sealing performance tester usually uses the negative pressure method for testing, that is, by vacuuming the inside of the package and observing whether there is gas leakage or expansion in the package, so as to judge its sealing performance. The following is an introduction to the sealing performance test of cosmetic glass bottles and soft packaging:

Test principle: The sealing performance tester generates an internal and external pressure difference inside the vacuum chamber, observes the gas escape from the sample or the expansion and recovery of the sample shape after the vacuum is released, and the liquid penetration, so as to determine the sealing performance of the sample.
Scope of application: The sealing performance tester is suitable for the sealing and tightness testing of cosmetic glass bottles, soft packaging bags, blister packaging and other products.

Technical features: Modern sealing performance testers usually have a microcomputer-controlled digital display of the test vacuum degree, digital preset test vacuum degree and vacuum holding time to ensure the accuracy of the test data. In addition, they also have an automatic constant pressure gas replenishment function to ensure that the test is carried out under preset vacuum conditions.
Operation steps: During the test, first install the sealing barrel on the base for preliminary debugging, select the appropriate air pressure, then inject clean water into the sealing barrel, put in the sample, cover the sealing cover, adjust the vacuum pressure gauge to the required pressure, observe whether there is continuous bubble overflow, and check the number displayed on the display through the pressure gauge.
Standard basis: The sealing performance test should comply with relevant national standards, such as GB/T 15171 "Soft Packaging Sealing Performance Test Method", etc., to ensure the authority and accuracy of the test results.
Importance: The sealing performance test is an important link to ensure the quality of cosmetic packaging. By adopting professional testing instruments and methods, the sealing performance of cosmetic packaging can be accurately evaluated, thereby protecting the health and rights of consumers.

Equipment selection: There are a variety of sealing performance testers available on the market, such as MFY-05A sealing tester (fully automatic), etc. They are suitable for the sealing and tightness testing of products such as flexible packaging bags, blister packaging, oral solid medicine bottles, external liquid bottles, butyl rubber plugs, glass bottles, etc.
