COF Tester is an advanced laboratory instrument designed to accurately measure the coefficient of friction of packaging materials such as plastic films, paper, foil, and laminates. It helps determine surface slip characteristics that directly affect machinability, stacking, and handling during packaging and printing processes.
Widely used in printing, flexible packaging, plastic film manufacturing, quality control labs, and R&D centers, COF Testers ensure compliance with industry standards and improve product consistency. Accurate COF measurement helps manufacturers optimize material performance, reduce production issues, and maintain high-quality standards.
