JH-YSBL type is specially suitable for testing the fastness of printing ink layer to plastic film and cellophane decoration printed matter (including composite film printed matter) produced by gravure printing process. It is also used for testing the adhesion state of the surface layer formed by vacuum coating, surface coating, lamination and other related processes.
The peeling angle and speed are designed in strict accordance with the national standards to effectively ensure the reliability and versatility of the detection data, the system is controlled by a microcomputer, with a PVC operation panel and LCD screen, which is convenient for users to quickly and conveniently carry out test operations and data display;
Automatic alarm prompt at the end of the test to ensure the user's operation safety;

JS C2107-1999 Test Method for Pressure-Sensitive Polyester Adhesive Tape for Electrical Insulation JIS Z0237-2000 Test Method for Pressure-Sensitive Adhesive Tape and Pressure-Sensitive Adhesive Sheet Test Principle:
The glass tape paper selected according to the standard and the printing surface of the sample ink after the test environment adjustment are bonded together with the standard load, rolling speed and rolling times, placed and adjusted for a certain time, and then they are peeled off with a certain pressure and peeling speed, and the condition of the ink layer of the sample is peeled off is observed, so as to judge and analyze the binding fastness of the printing ink layer.
