A method for improving the glossiness and ink color fastness of a printed color film is disclosed. The printed color film is a composite biaxially oriented polypropylene (BOPP) film. The method includes: (1) pre-treating the outer and inner surfaces of the composite BOPP film; (2) coating the outer and inner surfaces of the composite BOPP film with a surface-modifying coating agent and drying at a high temperature; and (3) printing the outer surface of the composite BOPP film with a water-based colored ink, and drying to obtain the printed color film. An application of the printed color film obtained by the method for tobacco packaging film to improve the glossiness and the ink color fastness of the printed color film is also disclosed.

A method for evaluating the possibility of a cigarette burning cone to fall off is disclosed. The method uses a manipulator simulation device to simulate the smoking of a cigarette, and measures the maximum deviation of the cigarette burning cone, and then uses angle summing and averaging to add the maximum deviations of the cigarette burning cones measured for multiple cigarettes and obtain an average value, and then evaluates the possibility of the cigarette burning cone to fall by the average value of the maximum deviations of the cigarette burning cone. The method is new, and compared with an existing method using state information of the cigarette burning cone 'falling' and “not falling,” the method can more accurately, directly and timely reflect the state of the cigarette burning cone.
