This invention relates to the field of heated cigarette technology, specifically disclosing a filter tip structure and molding method. The filter tip structure includes: a filter rod core, molding paper, and multiple plugs. The filter rod core is cylindrical, and the molding paper is fixedly sleeved on the outer circumferential surface of the filter rod core. The molding paper has multiple guide holes arranged in an array, with m rows along the circumference of the filter rod core and n columns along the axial direction of the filter rod core, where m and n are both integers greater than 0. The multiple plugs are arranged one-to-one with the multiple guide holes, and the plugs can block the guide holes. With this configuration, the smoker can manually remove the plugs before actually smoking. Removing the plugs increases the entry of side airflow, thereby increasing the ventilation rate of the heated cigarette and reducing the draw resistance during smoking. At the same time, removing the plugs can cause the microcapsules containing flavoring to rupture due to friction, releasing the flavoring and giving the smoke its characteristic aroma, effectively improving the smoker's smoking experience.
