摘要： A cigarette includes a charge or roll of smokable material (e.g., tobacco cut filler) circumscribed by two layers of paper wrapping materials. The first or inner wrapping material includes an inorganic filler material and tobacco material within the web. The inner wrapping material also can include a water soluble salt burn chemical and a carbonaceous material within the web. The second or outer wrapping material circumscribes and overwraps the first wrapping material, has a cellulosic base web and inorganic filler material, and exhibits a low inherent air permeability. The outer wrapping material can include a magnesium hydroxide filler, and exhibits an inherent air permeability of below about 15 CORESTA units and a net air permeability above about 40 CORESTA units. The cigarette is capable of sustaining smolder under FTC smoking conditions while yielding very low levels of visible sidestream smoke.

摘要： Cigarettes which yield low levels of visible sidestream smoke upon use employ an outer paper wrapping material including magnesium hydroxide, calcium carbonate and flax fibers. The outer wrapping material has an inherent permeability of about 10 CORESTA units. The wrapping material contains an amount of water soluble alkali metal salt sufficient to provide at least about 30 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt normally is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. The cigarettes also employ an inner paper wrapping material including carbonaceous material and/or tobacco.

The cigarette includes a filter element having 2 or more longitudinally positioned segments, and one of the segments includes a carbonaceous material.
摘要翻译： 香烟包括由两层纸包装材料包围的可吸烟材料（例如烟草切割填料）的卷或卷。 第一或内包装材料包括无纺填充材料和卷材内的烟草材料。 内包装材料还可以包括水溶性盐燃烧化学品和网内的含碳材料。 第二或外包装材料围绕和覆盖第一包装材料，具有纤维素基底料和无机填料，并且具有低的固有透气性。 外包装材料可以包括氢氧化镁填料，并且具有低于约15CORESTA单元的固有透气性和高于约40CORESTA单元的净透气度。 香烟在FTC吸烟条件下能够持续闷热，同时产生非常低水平的可见侧流烟雾。 香烟包括具有2个或更多个纵向定位的段的过滤元件，并且其中一个段包括碳质材料。
