Effects of cigarette materials on mainstream smoke delivery and filtration efficiency of cigarette with 27 mm filter rod

Effects of cigarette materials,such as cigarette paper,tipping paper,wrapping paper,and filter rod,on mainstream smoke delivery and filtration efficiency of the cigarette with 27 mm filter rod were studied by orthogonal experiment.Results indicated that the most prominent and important factors affecting mainstream smoke delivery were air permeability of tipping paper and pressure drop of filter rod,and those affecting filtration efficiency were air permeability of wrapping paper and pressure drop of filter rod.Therefore,the adjustments and control of those factors was key to cigarette quality control cost reduction,which was a quick,efficient,economical,and precise method.
