Title:
CIGARETTE FILTER ROD AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/088159
Kind Code:
A1
Abstract:
A cigarette filter rod, which is a gathered thin film (1). The thin film is provided thereon with discretely distributed indentations (5) and discretely distributed cracks (7) that penetrate the thin film. The indentations are long strip-shaped. When an external force is applied in the horizontal direction of the thin film, the thin film is mesh-like. A method for preparing the cigarette filter rod comprises: press-cutting a thin film for cigarettes into a plurality of indentation and crack-shaped thin films by means of a press-cutting device, and then gathering the thin films to form a filter rod. Since the thin films have cracks, the speed with which smoke penetrates the filter rod is increased, which reduces the amount of stagnation of smoke in the filter rod, increases the amount of smoke entering the mouth of a smoker, and improves the smoking sensation for the smoker.
