An aerosol-generating article is provided for producing an inhalable aerosol upon heating, the article including: a rod of aerosol-generating substrate extending from a rod proximal end to a rod distal end upstream from the proximal end, the substrate an aerosol-former, an aerosol former content of the substrate being at least 10 percent on a dry weight basis; a downstream section located downstream of the rod; and a wrapper circumscribing the rod, the wrapper including a wrapping base material having a dry basis weight, in which a treated portion of the wrapper extending between the proximal and distal ends includes a flame retardant composition including flame retardant compounds, such that the treated portion has an overall dry basis weight greater than that of the wrapping base material, and in which the treated portion includes at least about 2 g/m.sup.2 of the flame retardant compounds of surface area of the treated portion.

A paper comprises from 60 to 99 weight percent of a aramid fibrous pulp and from 1 to 40 weight percent of a polyvinylpyrrolidone coating on the fiber surface, the coating being neither chemically nor electrostatically bound to the fibers. A friction paper composite comprising the paper and a resin coating is also described.

A method of forming a coating on a cylindrical paperboard container having a closed end. The method includes the steps of heating a gas from a first temperature to a second temperature; providing the gas to a first inlet of a nozzle; providing a polymer in a liquid state at a third temperature; providing the polymer to a second inlet of the nozzle; and spraying the polymer onto the cylindrical paperboard container using the nozzle; wherein the second temperature is greater than the third temperature; and the second temperature and third temperature are such that the gas maintains the polymer in the liquid state at least until the polymer comes into contact with the cylindrical paperboard container. A system for applying a coating to a plurality of cylindrical paperboard containers and a container for a consumer product are also provided.

Processes for imparting oil and grease resistance to paper products. In some embodiments, the process can include combining a plurality of fibers and water to produce a slurry; forming the slurry into a wet web; pressing and draining the wet web to produce a wet sheet; and drying the wet sheet to produce a dried sheet. A sizing composition and a barrier compound can independently be applied to at least one of the slurry, the wet web, the wet sheet, and the dried sheet. The sizing composition can include one or more alkenyl succinic anhydride compounds. The barrier compound can include a polyolefin dispersion, a styrene acrylate emulsion, a sucrose ester, a modified starch, styrene maleic anhydride, an ethylene acrylic acid dispersion, a styrene acrylic acid, a polyvinyl alcohol, an ethylene vinyl alcohol, or a mixture thereof. The dried sheet can have an average KIT Value of at least 3.
