PE bottles are usually used to package food, medicine, cosmetics and other products. With good chemical resistance, impact resistance and barrier properties, PE bottles can well protect the contents of the package and maintain their quality and taste. Therefore, it is very important to test the oxygen permeability of PE bottles.
PE bottle oxygen permeability tester is commonly used to test the oxygen permeability performance of PE bottles, and the following is introduced in detail from many aspects such as working principle and equipment characteristics.
The working principle of the PE bottle oxygen transmittance tester:
The treated sample is clamped on the test chamber, oxygen or air flows on one side of the film, high-purity nitrogen flows on the other side of the film, oxygen molecules diffuse through the film to the high-purity nitrogen on the other side, and the flowing nitrogen is carried to the sensor, and the oxygen concentration measured by the sensor is analyzed, and the oxygen permeability test data is issued after reaching the osmotic equilibrium.
PE Bottle Oxygen Transmittance Tester Features:
The PE bottle oxygen transmittance tester is equipped with a high-precision coulomb oxygen sensor, which improves the accuracy and stability of the test. The instrument is fully automated, and the operation interface is very intuitive and easy to operate. It can meet the test under various test conditions, and the test results can be saved and exported, and single and multiple repeated tests can be supported.
Summary. By using the oxygen transmittance tester of PE bottles, the product quality of PE bottles can be effectively ensured, which is conducive to improving production efficiency and better protecting the shelf life of products.
