GB/T 14216-2008 "Determination of Wetting Tension of Plastic Films and Sheets" standard specifies the method of measuring the surface wetting tension of Plastic films or sheets using specific test solvents. The standard emphasizes the importance of Plastic film surface characteristics for the retention capacity of inks, coatings, adhesives, etc., and the feasibility of improving wetting tension through surface preparation techniques. The standard also states that contaminants, traces and impurities in reagents on the film surface can affect the measurement results of wetting tension, so it is required that the test equipment and reagents must be kept clean and high purity. In addition, since the film surface performance varies with time, the test conditions and the offline time of the sample need to be recorded during the test. However, this standard does not apply to specimens that react chemically with the test solvent, and to ensure the accuracy of the test results, the specific steps in the standard should be followed and the measurement should be carried out.
