| Summary: | There is a proportional dependence between pressure difference and air stream of porous cigarette papers. In the case of perforated papers, however, the said relationship conforms to a non-linear function. It is therefore important to measure the permeability to air of these papers under a pressure difference that corresponds to the actual pressure conditions in cigarettes, i.e. approximately 0.25 dm water column gauge. With identical air permeability and identical degree of ventilation the yields of condensate, nicotine and phenols in the mainstream smoke of cigarettes made with porous paper decrease to a larger extent than the yields of the mentioned substances in the mainstream smoke of cigarettes made with perforated paper. |
