ABSTRACT:
A vented filter cigarette with a filter having a fiber filter material and a plug wrap paper wrapping the fiber filter material, a tobacco rod, and tipping paper having a plurality of pores and connecting the filter and the tobacco rod. An embossment is formed in a region of the plug wrap paper corresponding to the pores of the tipping paper. The embossment creates a slight gap between the tipping paper and the circumference of the filter around the pores, with the result that the tightness between the tipping paper and the circumference of the filter is loosened, the filter ventilation is increased, and the variation in the filter ventilation is decreased.
