The coefficient of friction is the ratio of the friction between two surfaces to the normal force acting on one surface. It is related to the roughness of the surface and not to the size of the contact area. Depending on the nature of the movement, it can be divided into a dynamic coefficient of friction and a static coefficient of friction. The sliding friction force is generated by the relative sliding of two objects when the two objects are contacted with each other.
The friction coefficient is an important index in the field of cigarette package printing, and the friction coefficient of the surface of a printed matter is one of main influence factors of the operation speed of a packaging machine and the easiness in opening of a package, because the friction force in the packaging process is usually power and resistance, the friction force is controlled in a proper range. When there is relative motion or relative motion trend between two objects in contact with each other, the mechanical force generated on the contact surface of the two objects to resist the relative motion is friction. The friction properties of a material can be characterized by the coefficient of friction of the material.
