The Digital Coefficient of Friction (COF) Tester is a precision testing instrument designed to measure the frictional properties of packaging materials and determine their sliding resistance. It evaluates the static and dynamic friction characteristics of material surfaces to ensure smooth handling, stacking and packaging performance. The instrument features a digital LED display, a 3 kgf load cell capacity and a controlled testing speed for consistent measurement results. It is suitable for testing plastic films, packaging sheets, paper, laminates and other flexible packaging materials. This tester is widely used in packaging industries, quality control laboratories and material testing facilities.
