To further perfect the system of material barrier property data, Labthink Languang will take full advantage if its data cumulated during lab tests in the past years by setting up a complete database for auto gas permeability testing. Taking film as the research object under a very wide temperature range, this database can be shared globally through network.
Since its establishment in 2000, Languang barrier property lab has enjoyed a rapid development. It is furnished with auto gas and water vapor permeability instruments that based on various testing methods (For example, auto gas permeability instruments of differential-pressure method and water vapor permeability instruments of gravimetric method, sensor method, infrared method and electrolytic method), which has covered most of the test methods used in ISO, ASTM and international barrier property testing of materials. Moreover, Languang has cumulated abundant valuable testing data of various polymer barrier materials through its experience of providing material testing to customers and through data comparison and commutative testing with international well-known labs. To make full use of the above-mentioned resources and to better its service to flexible package industry, Languang hit upon the idea to set up a database of barrier property parameters.
After a series of processing of complex film, the referencing value of its barrier property data becomes rather smaller. Therefore the research of film auto gas permeability testing has a greater significance. In addition, since temperature fluctuation is the main factor influencing material barrier property and it is also an important parameter that has an obvious change in the application environment of material, Labthink lab will mainly carry out film testing under different temperature during the initial setting up period of barrier property database, including film barrier property parameters obtained with data fitting from deep cooling temperature to vitrification point.
This database will provide great conveniences and supports to the manufacturing, using, testing and research of flexible package. First, featuring with rich data and convenient enquiry, this database can provide efficient data reference to customers in aspects such as product research and development, material choosing. Second, global data sharing and data comparison after setting up of database provides opportunities of more intercommunication with fellow members of this industry. Next, having the function to test data under special temperature can offer customers with such services.
Polymer material is widely used in flexible package. Starting from the material that is used most commonly with the most stable property, Languang will make a constant improving of its database. We will provide updated information about the database in time and your pleasure of attention is warmly welcomed.
