The filler particles may comprise kaolin clay, magnesium oxide, mica, alum, or mixtures thereof.

Abstract: Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a paper wrapper containing cellulosic fibers and filler particles. The paper wrappers are formed so that the filler particles form a concentration gradient throughout the thickness of the wrapper. More particularly, a greater concentration of filler particles are present at a first surface in comparison to the amount of filler particles present at the opposite surface. In accordance with the present disclosure, an ignition reducing composition is applied to the first surface. In this manner, treated areas having more uniform properties are formed.

Abstract: The present invention is directed to smoking articles having reduced carbon monoxide delivery are described. A carbon monoxide reducing agent is incorporated into the smoking article in order to reduce carbon monoxide levels in mainstream smoke. The carbon monoxide reducing agent may be, for instance, in metal oxide or in metal carbonate. The carbon monoxide reducing agent may be incorporated into a wrapper and/or into a column of smokable filler that are used to construct the smoking article.

Abstract: Smoking articles having reduced Hoffmann analytes contained in the mainstream smoke is disclosed. In one embodiment, an alginate composition is applied to a wrapper that is incorporated into a smoking article. The alginate composition causes a significant reduction in at least certain of the Hoffmann analytes that are generated when the smoking article is smoked. The alginate composition may be applied so as to cover a substantial portion of the surface area of the wrapper in one embodiment. In another embodiment, the alginate composition is applied as a single band to the paper wrapper so to cover a substantial portion of the distal end of the smoking article.

Abstract: Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a paper wrapper containing cellulosic fibers and filler particles. The paper wrappers are treated with a film-forming composition in order to reduce the ignition proclivity characteristics of the smoking articles. In one embodiment, the film-forming composition contains an alginate combined with a starch. In an alternative embodiment, the film-forming composition contains a film-forming material combined with filler particles. The filler particles may comprise kaolin clay, magnesium oxide, mica, alum, or mixtures thereof.

Abstract: Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a wrapper comprising cellulosic fibers and a filler. In accordance with the present disclosure, the filler has a particle size of at least about 3.2 microns and is present in the wrapper in an amount less than about 20% by weight. Further, the wrapper may have a basis weight of less than about 23 gsm and a permeability of from about 15 Coresta to about 110 Coresta. It has been discovered that such wrappers are capable of reducing the ignition proclivity characteristics of a smoking article. If desired, the particular wrapper as described above can also contain discrete areas treated with an ignition reducing composition which further serves to reduce the ignition proclivity characteristics of the article.

Abstract: The present invention is generally directed to smoking articles having reduced carbon monoxide delivery. In order to reduce carbon monoxide delivery, the wrapping papers used to construct the smoking article has a fiber basis weight of less than about 18 gsm. Smoking articles constructed in accordance with the present invention can have a carbon monoxide delivery less than about 18 mg per smoking article.

Abstract: A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition contains a film-forming material. The film-forming material has a relatively low viscosity. In this manner, the film-forming composition can have a relatively high solids content and still be applied to the wrapper using conventional techniques, such as by using a gravure printer.

The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition is applied as multiple layers to the paper wrapper. After each application step, the wrapper is dried. Applying the film-forming composition to the paper wrapper in multiple layers minimizes distortion and other adverse affects that may occur to the wrapper.

The wet strength properties of the paper are increased by incorporating into the paper an alkyl ketene dimer and by applying a size containing polyvinyl alcohol to a surface of the paper. The wet strength properties of the paper can be increased without using cross-linking agents. Porous plug wrap papers made in accordance with the present invention can have a wet tensile strength retention of at least 20%.

Abstract: The present invention is directed to a method for improving the ash characteristics of a paper wrapper for a smoking article and for improving the ash characteristics of the smoking article itself. Specifically, it has been unexpectedly discovered that the ash cohesiveness of a paper wrapper is noticeably improved when carbon fibers having an average length less than about 0.75 inches are incorporated into the paper in an amount up to about 60% by weight. Paper wrappers made with carbon fibers in accordance with the present invention have superior ash characteristics in comparison to paper wrappers incorporating only flax or other cellulosic fibers. Further, the ash cohesiveness of the paper is improved without resulting in the decline in the quality of other ash characteristics.

For instance, such paper wrappers formed according to the present invention typically have a Diffusion Conductance Index (DCI) of less than about 15 cm−1 and a Static Burn Rate (SBR) of less than about 5 millimeters per minute.
