To avoid the product defects caused by the friction marks in cigarette carton film, the molding passage of YB95A carton overwrapper was improved. When the particle plate was welded on the surface of the channel and the first lifting structure for forming was designed to rolling-folding, the friction that the transparent paper bore in the process of wrapping and transporting was greatly reduced. The application of new material and new structure demonstrated that the rate of carton film with friction marks decreased from 49.21% to 3.49% after the improvement and these quality defects had been effectively solved.
