COF Tester for Plastic Films and Flexible Packaging The coefficient of friction is a critical property that affects the stability of product manufacturing and transportation. It determines how the film moves on processing equipment, how packaging materials are conveyed and stacked, and whether automated packaging operations can remain stable. Saicheng’s coefficient of friction tester can measure both static and dynamic coefficients of friction, making it suitable for determining the friction coefficients of plastic films, laminated films, aluminum foil, paper, coated materials, and other flexible substrates. Why Test the Coefficient of Friction? If the coefficient of friction is too high, greater resistance is encountered during conveyance, which affects the smooth flow of material and can easily lead to sticking issues. Similarly, if the coefficient of friction is too low, problems such as slippage,

inaccurate positioning, and stacking difficulties are likely to occur. By measuring the static and dynamic coefficients of friction with a friction tester, one can evaluate a material's friction characteristics in real-world production scenarios and avoid production issues caused by substandard friction behavior. Coefficient of friction testing can be applied to: • Plastic packaging films • Multilayer and laminated films • Flexible packaging materials • Aluminum foil and coated foil • Printed and coated substrates • Materials used in automated packaging lines COF testing can be used for new material...
