Barrier property testing includes permeability testing of oxygen, water vapor and fragrant gas through cosmetic packages.

The unsaturated bonds in cosmetic ingredients are easy to be oxidized and deteriorated; the lost of moisture in the cosmetic would lead to hardening of cosmetics. Meanwhile, the fragrance of the cosmetics has great influence on the marketing of cosmetics.

• Oxygen Permeation Testing: This index is mainly for the oxygen transmission rate testing of films, laminated films, cosmetic pouches or bottles. Hereinafter, we take Labthink PERME OX2/230 Oxygen Transmission Rate Test System as the example. Clamp the preconditioned specimen in between the testing chamber, oxygen/air flows in one side of the film, and high pure nitrogen flows in the other side. Oxygen molecules migrate through the film and into the high nitrogen side, and are carried by the nitrogen flow to the sensor. With the oxygen concentration analysis of the sensor, the oxygen transmission quantity can be calculated. The testing principles of pouches and bottles are similar.

• Water Vapor Transmission Rate Testing: is mainly for the testing of water vapor transmission rate of film materials and packaging containers like bottles, bags and cans. Through WVTR testing, technical indexes for control and adjustment of packaging materials can be achieved so as to meet the varied application needs. Take PERME W3/330 Water Vapor Transmission Rate Testing System as an example. Clamp the specimen in between the testing chamber, a flow of constant stable nitrogen flows in one side of the film and dry nitrogen flows in the other side. Owing to the humidity difference, water vapor would penetrate from the high humidity side into the low humidity side. The penetrated humidity (moisture) is carried by the dry nitrogen to the sensor, outputs electronic signal and then, calculates water vapor permeability quantity. For packaging bags and bottles, dry nitrogen flows inside the container and the outside is in high humidity state.

• Fragrance Maintenance Testing: This Index is very important to cosmetics. Once the fragrance loses, there would be great influence on selling. Take PERME OR2/410 Organic Gas Transmission Rate Test System as example. In regulated temperature, separate the chamber into two halves by the specimen, with one side as dense fragrance side and the other low concentrated fragrance side; thus, forming a concentration difference between two sides. Fragrant gas will penetrate into the low concentration side and be carried to the isolation chamber by the carrying gas. Hydrogen flame ionization detector (FID) can measure the quantity of the fragrance gas and further calculate the fragrance gas quantity in a unit area within a unit time.

1. Gas and Vapor Transmission Testing and Analysis of Dairy Flexible Packaging Materials

• The gas and water vapor transmission property tests of dairy packaging materials are of vital importance in dairy industry. Mocon, PBI and PERME OX2/230 Oxygen Transmission Rate Test System can all test the relevant indexes. Labthink PERME OX2/230 Oxygen Transmission Rate Test System is of coulometric principle and equal pressure method for the oxygen transmission property testing of film, sheets and containers (bottles, bags, cans and boxes). This system is advanced in its function and accuracy: master base-satellite mode, one master base can connect 9 satellite bases so as to realize simultaneous testing of 30 specimens with greater testing efficiency.

2. Testing and Analysis of the Heat Seal Strength of Dairy Flexible Packages

• Heat seal is an important index for packaging materials. Labthink XLW (PC) Auto Tensile Tester can accomplish this task professionally. This instrument can automatically read the data and automatically judge the strength value as well as carry out data superposition of the same specimen group.

3. Testing and Analysis of Coefficient of Friction of Dairy Flexible Packaging Materials

• The coefficient of friction tests are for control and adjustment of open easiness of flexible packages as well as packing speed of packing machines, and other production quality and processing indexes. Labthink MXD-02 Coefficient of Friction Tester is multi-method applicable so as to resolve the problem of method confusion for the manufacturer.

4. Leakage Testing and Analysis of Dairy Package

• Leakage is an important index for dairy products, and has great influence on product quality. Inferior sealing performance is the main cause of the following leakage and deterioration. With Labthink LSSD-01 Leak and Seal Strength Detector, we can evaluate the quality of the packages and judge the corresponding sealing processing.

5. Testing and Analysis of Composite/Bond Strength of Dairy Packaging Materials

• Qualified and cost-saving composite material needs to undergo quality testing analysis of the layers so as to find proper composition indexes. Labthink Auto Tensile Tester Manufactured is specializing in the test of flexible package line and in compliance with relevant ASTM, ISO and Chinese GB standards.

6. Other Quality and Analysis of Dairy Packages

• The well-printed dairy packages will definitely attract the sight of more customers and expand market share.  Labthink YGJ-02 Adhesive Tensile & Shear Tester and BLJ-02 Disk Stripping Tester can be adopted so as to achieve quality control purpose in printing and color.
