Wrapper for cigarette manufacture includes transversely extending band regions applied by a printing technique, such as gravure printing. The band regions comprise starch, an anti-wrinkling agent such as 1,2 propylene glycol or glycerin, and optionally calcium carbonate. Any suitable printing technique can be used to apply the aqueous solution to the banded regions. The pattern of banded regions may be bands, stripes, two-dimensional arrays, undulated regions, and the like along and/or around the tobacco rod. The pattern can be applied in one or more layers. The pattern may be configured so that when a smoking article is placed on a substrate, at least two longitudinal locations along the length of the tobacco rod have film-forming compound located only on sides of the smoking article not in contact with the substrate.

A process for preparing coated particles of a plant material includes: (a) combining plant material particles and a protein in a liquid medium, wherein the protein adsorbs onto at least a portion of a surface of the particles to form a first layer; and (b) mixing a polysaccharide including a pectin with the liquid medium, so that the polysaccharide adsorbs onto at least a portion of a surface of the first layer to form a second layer. In addition, a palatable product comprising at least one coated particle prepared by this process is described.

The invention relates to a reconstituted tobacco sheet having a basis weight of less than about (14) grams per square foot (about (151) grams per square metre) and comprising tobacco stem or stalk refined fibres having a length of at least about (300) micrometres and tobacco cast leaf material. There is further provided a method of making a reconstituted tobacco sheet, the method comprising preparing a dispersion of tobacco stems or stalks in a liquid, the dispersion having a consistency of at least about (10) percent by weight. The tobacco stems or stalks in the dispersion are refined to obtain a pulp suspension having a freeness (drainability) of at least about (30) degrees Schopper-Riegler and comprising tobacco stem or stalk fibres having a length of at least about (300) micrometres dispersed in the liquid. The pulp suspension is combined with tobacco cast leaf material to obtain a slurry, and a sheet is formed from the slurry.

Reconstituted tobacco sheets and related methods

A filter rod comprises a core of cellulose acetate fibers surrounded by a lofty porous network of charge retaining polymer fibers. The charge retaining fibers can be charged to attract and hold particles from such sources as particulate matter from sorbents (preventing break-through), and smoke constituents while having a suitable pressure drop.

Filter rod including electrostatically charged fibers

Provided are a method and apparatus for making a cigarette filter assembly for potentially reducing particle breakthrough. The method includes forming a lofty porous network of charge retaining polymer fibers by mechanical, chemical or thermal bonding of the fibers, wrapping the lofty porous network in a cylindrical or tubular shape with optional mediating filter fibers in a filter paper to form a filter plug while maintaining the lofty structure. The charge retaining fibers can be charged to attract and hold particles from such sources as particulate matter from sorbents (preventing break-through), and smoke constituents while having a suitable pressure drop. The apparatus handles the lofty media with minimal crushing, for example, by spacing apart delivery rolls equipped with protrusions to punch, push, and/or pull the lofty media ahead for high speed operation.

Oral tobacco products having a gel-coating and methods for making are provided. The method includes (a) molding a portion of tobacco material to form a pre-portioned piece of tobacco material, the tobacco material comprising moist smokeless tobacco; (b) contacting the pre-portioned piece of tobacco material with a gel-coating solution to form a gel-coating comprising at least one polymer on an outer surface of the pre-portioned piece of tobacco material to form a gel-coated oral tobacco product, said gel-coating comprising an inner surface disposed around the pre-portioned piece of tobacco material and an outer surface; and (c) forming one ore more of perforations, uncoated areas and holes in the gel-coating of the oral tobacco product to form a gel-coated oral tobacco product.
