GB/T 33049-2016 "Optical Films for Polarizers - Test Method for Coating Adhesion" specifies the test method for determining the adhesion of coatings on optical films used for polarizers, and it is applicable to quality inspection of related optical film products. The testing is conducted using methods such as the cross-cut test and tape peel test, where the adhesion level is assessed by observing the degree of coating detachment. The test requires the use of a cross-cut tester, standard adhesive tape, a magnifying glass, or a microscope. During the test, parameters such as the depth of the cross-cut and the pressure applied during tape adhesion must be controlled to ensure the accuracy and comparability of the test results.
