Working in for all intents and purposes about each feature of our lives, rubbing is the imperceptible power that permits, or obstructs the development of two surfaces that are in contact with each other. Coefficient of Friction is the proportion of the power that keeps up contact between a protest and a surface and the frictional power that opposes the movement of the question. A bundling film's "coefficient of rubbing" (COF) gives an overall sign of frictional attributes. Controlling COF enables processors to upgrade execution and dodge issues in framing, transporting, and putting away of bundles.
