Provided herein are a coating composition of a low ignition propensity cigarette paper, a smoking article using the same, and a method of manufacturing the low ignition propensity cigarette paper. The coating composition of the low ignition propensity cigarette paper according to some embodiments of the present disclosure includes Arabic gum, ethanol, water, and fructo-oligosaccharide. Fructo-oligosaccharide may remarkably delay the aging speed of the coating composition and block even fine pores so that the ignition propensity of the coating composition is significantly reduced.

There is provided an aerosol generating article (2) comprising a combustible heat source (4) having an upstream portion and a downstream portion. The aerosol generating article further comprises an aerosol-forming substrate (10) downstream of the heat source (4) and a wrapper (36) circumscribing an upstream portion of the aerosol-forming substrate (10) and the downstream portion of the combustible heat source (4). The aerosol generating article (2) further comprises a non-combustible coating (42) provided on the upstream portion of the combustible heat source (4) and not on the downstream portion of the combustible heat source (4), the non-combustible coating having a thickness of between about 30 micrometres and about 250 micrometres.

A wrapper for a smoking article has a base web and a plurality of elements each having at least a pair of patch areas where diffusivity is in the range of 0 to about 0.2 cm/sec. Patches of adjacent elements are circumferentially offset from one another along the axis of a smoking article. The add-on material can be applied by gravure printing in a single pass in a chevron pattern such that an apex of the element is co-linear with substantially symmetrically spaced points on a trailing, outer edge of an adjacent element. Testing elements may be simultaneously printed with the add-on material to monitor diffusivity and/or presence of add-on material.

A wrapper 10 for an aerosol-generating article includes at least one coated surface area and at least one non-coated surface area, wherein the coating of the at least one coated surface area of the wrapper is heat-sensitive, wherein the coating indicates heat application by a permanent color change. An aerosol generating article includes such a wrapper. A method for producing an aerosol generating article includes such a wrapper by printing a polymer on parts of the wrapper by flexography.

A cigarette rolling paper system that incorporates a nicotine laden marking in the inside portion of the paper. The system integrates combustible material laid out in parallel to the nicotine laden mark. The system also has adhesive section on one edge that comes to meet the other edge to contain the combustible material and roll up into a cylindrical shape. The method of using the system envisions laying out the cigarette paper flat on a surface with the nicotine laden mark facing up. Then the user places the combustible material parallel to the mark along the length of the cigarette paper. Then the user rolls up one side of the cigarette paper to meet the other side along the length of the cigarette paper. The edge of one side of the cigarette paper has adhesive material that contacts the other side and thus secures the contents. The rolled up cigarette paper is thus retains a cylindrical shape.

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 rolling paper includes a hydrophobic substrate region comprising hydrophobic groups covalently bonded to the rolling paper, and a moisture-activated adhesive adjacent to the hydrophobic substrate region and longitudinal edge of the rolling paper.

A smoking article is disclosed herein. The smoking article includes a shell defining an interior space, a consumable substance within the interior space, a heat source effective to increase the temperature of at least a portion of the shell, and a label attached to at least a portion of the shell. The label includes a base film, a cover film, and a temperature dependent material disposed between the base film and the cover film. The temperature dependent material is configured to transition between a first appearance and a second appearance responsive to the increase of the temperature of at least a portion of the shell.

Provided herein is a smoking article from which sound is generated. The smoking article according to some embodiments of the present disclosure may include a filter portion and a smoking material portion, and a sound-generating material including a carbohydrate material may be added to the smoking material portion. The sound-generating material may generate sound as the material burns, and the sound may further provide an auditory effect during smoking. In this way, an improved smoking experience may be provided to the smoker.

The method for manufacturing a wrapped endless rod of substantially flat continuous material comprises the steps of providing a substantially flat continuous material, treating the substantially flat continuous material with corona discharge and forming the corona treated substantially flat continuous material into an endless rod. Further steps comprise providing a wrapper, applying adhesive to the wrapper and wrapping the endless rod with the wrapper. Therein the step of applying adhesive to the wrapper comprises applying adhesive over a width of the wrapper and in a central portion of the wrapper.
