Coefficient of friction calculation is essential for understanding the frictional behavior of materials when two surfaces come into contact. The COF is determined by dividing the frictional force by the normal force. This measurement helps assess the sliding and slip properties of materials used in packaging and manufacturing applications. COF testing is commonly applied to paper, plastic films, sheets, and other surfaces. Accurate results enable manufacturers to evaluate material performance, optimize processing, and ensure consistent quality.
