摘要： Cigarettes which yield low levels of visible sidestream smoke upon use employ a paper wrapping material having about 25 weight percent magnesium hydroxide, about 15 weight percent calcium carbonate and about 60 weight percent flax. The wrapping material has an inherent permeability of about 12 CORESTA units and a net permeability of about 100 to about 130 CORESTA units. The wrapping material containing an amount of water soluble alkali metal salt sufficient to provide at least about 35 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. the cigarettes, when employed, provide cohesive ash which is not highly flakey.

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 have a tobacco rod including smokable material circumscribed by a paper wrapper. The paper wrapper includes a cellulosic base web (e.g., flax and/or wood pulp fibers) and particles of at least one inorganic filler material. The inorganic filler material includes calcium sulfate, and normally fibers of calcium sulfate having an aspect ratio of about 30.

摘要： Cigarettes which yield low levels of visible sidestream smoke upon use employ a paper wrapping material having about 30 weight percent calcium carbonate and about 70 weight percent flax. The paper wrapper includes a coating or a film of polymeric material and an organic filler material. A preferred polymeric material is nitrocellulose, and a preferred inorganic filler material of the coating is particulate magnesium hydroxide. The coating weighs about 0.05 to about 0.5 pound per 3,000 square feet of wrapping material.
摘要翻译： 使用时产生低水平的可见侧流烟的香烟使用具有约30重量％碳酸钙和约70重量％亚麻的纸包装材料。 纸包装纸包括聚合物材料的涂层或薄膜和有机填料。 优选的聚合物材料是硝化纤维素，并且涂层的优选的无机填料是颗粒状氢氧化镁。 涂层重约0.05至约0.5磅/ 3,000平方英尺的包装材料。
