Abstract
A method for manufacturing and packaging a special-shaped cigarette includes the following steps: designing inner packaging case paper capable of being folded into a special-shaped cigarette accommodating cavity; folding the inner packaging case paper to form the special-shaped cigarette accommodating cavity; filling an interior of the special-shaped cigarette accommodating cavity with an ordinary cigarette; and shelving for a certain period of time, so that a cross section of the ordinary cigarette changes from a circle to a special shape, and the ordinary cigarette is accommodated in the special-shaped cigarette accommodating cavity. A diameter of an inscribed circle of the special-shaped cigarette accommodating cavity is less than a diameter of the ordinary cigarette, and a material of the inner packaging case paper is a paperboard or a food grade PVC sheet.
