Abstract

A vented filter cigarette comprising: a filter having a fiber filter material and a permeable plug wrap paper wrapping the fiber filter material, the plug wrap paper having a Coresta permeability of 1000 or more; a tobacco rod; and tipping paper having a plurality of pores and connecting the filter and the tobacco rod. The permeable plug wrap paper has a ventilation area which face the pores and through which dilution air from the pores passes. An embossment having grooves of a grid-pattern is formed on the plug wrap paper at least in the ventilation area and not to reach either end of the plug wrap paper, in order to loosen tightness between the tipping paper and the plug wrap paper in the ventilation area to control filter ventilation of the cigarette and to reduce variation in the filter ventilation.
