Differential pressure container gas permeability tester

With the development of flexible packaging, the application of plastic containers in the packaging industry has become more and more extensive. Coke beverage bottles and PET beer bottles can be seen everywhere. Because the oxygen barrier performance of the outer packaging directly affects the shelf life of the products, the requirements for standardized testing of the oxygen permeability of packaging containers are very urgent.

The traditional oxygen permeability testing method is to make the material into a sheet for experiment, and the thickness of the bottle body after making a bottle container is not appropriate. The data for the sheet testing can represent the oxygen permeability of the entire container, and the manufacturer is skeptical. Industry experts also believe that using only partial oxygen permeability to assess the oxygen barrier performance of the entire container, the point of view is not scientific enough. Therefore, the oxygen permeability test of plastic containers has always been a major problem in the industry.

Recently, Jinan Languang Electromechanical Technology Co., Ltd. has come out with the “G2/130 Differential Pressure Vessel Gas Permeability Tester”, which is the first domestic testing instrument that uses the differential pressure test principle to test the overall gas permeation performance of the container. The advent of this instrument effectively solved this problem. The instrument is a patented invention of Jinan Languang. It adopts the Intel central processor to determine the overall gas transmission rate of various hollow packaging containers by vacuum degassing on both sides of the container. Test gases include air, oxygen, nitrogen, carbon dioxide, and the like.
