Definitions
- the present invention relates to a wrapping paper for a smoking article that has a low ignition propensity and a smoking article comprising a wrapping paper that has a low ignition propensity.
- US 2013/104,915 teaches a cigarette paper that provides a cigarette manufactured therefrom with self-extinguishing properties, wherein the base paper has a CO 2 diffusivity of less than 0.35 cm/s and the cigarette paper comprises at least one discrete area, wherein this area is perforated and has an air permeability greater than the air permeability beyond the perforated area.
- US 2016/198,761 relates to a cigarette paper with self-extinguishing properties that has treated areas, onto which a composition is applied that contains filler particles or a mixture of filler particles, wherein the diffusion capacity in the treated areas is less than in an untreated area of the cigarette paper.
- at least 20% by weight of the filler particles in the treated areas are formed by a filler with a flaked shape, a filler with a scalenohedral crystal structure, a filler with a rhombohedral crystal structure, or a filler with a cubic shape.
- Japanese Utility Model No. 3049857 discloses a cigarette wherein the length of the tobacco rod is half that of the ordinary cigarette. Also Japanese Patent Application KOKAI No. 7-327654 discloses a cigarette wherein the length of the tobacco rod is decreased to 1 to 1.5 cm in order to prevent a fire and to suppress the sidestream smoke. These cigarettes having a shorter than usual tobacco rod provide a number of puffs considerably smaller than that provided by the cigarette available on the market.
- the problem of the present invention is to provide a wrapping paper for a smoking article that has a low ignition propensity and a reduced impact on taste.
- US 2012/0227754 discloses a smoking article which includes a smokable rod manufactured using a paper wrapping material having an additive material applied thereto as a pattern.
- the wrapping paper includes at least one region coated with an additive material coating formulation having a porosity of less than about 20 CORESTA and a diffusion capacity no greater than 0.2 cm/sec.
- the coated region is on a base sheet having a porosity of greater than about 120 CORESTA and a diffusion capacity of at least 1.7 cm/sec.
- the inventors have found that by providing a wrapping paper for a smoking article with a plurality of burn-suppressing regions and a certain ratio of diffusion capacity between the burn-suppressing regions and the base paper, i.e. the non-burn-suppressing regions, it is possible to obtain a low ignition propensity smoking article with a reduced impact on taste.
- a first aspect of the present invention relates to a wrapping paper comprising a base paper, where the base paper comprises a plurality of burn-suppressing regions that are provided apart from each other, wherein the ratio of diffusion capacity between the burn-suppressing regions and the base paper, i.e. the non-burn suppressing regions, is in the range of 5% to 35%.
- a smoking article comprising a charge of smokable material surrounded by a wrapping paper according to the first aspect of the invention.
- the smoking article is in particular a low ignition propensity smoking article.
- FIG. 1 is a schematic perspective view, partly broken away, showing an example of a cigarette that is wrapped with a cigarette paper having stripe-shaped burn-suppressing regions according to one embodiment of the present invention.
- the cigarette 10 has a tobacco rod 11 consisting of a tobacco filler 13 that is wrapped with a wrapping paper 12 of the present invention in the form of a column.
- An ordinary filter 15 may be attached to the proximal end (namely, the downstream end in the inhaling direction) 11b of the tobacco rod 11 by using a tipping paper 14 according to a conventional method.
- a plurality of stripe-shaped burn-suppressing regions 122 which are coated as will be explained in the forthcoming description, are formed on one of the surfaces of the base paper 121 that constitutes the wrapping paper 12 of the present invention. These stripe-shaped burn-suppressing regions 122 are formed apart from each other in the circumferential direction of the tobacco rod 11.
- Non-burn-suppressing regions 123 are formed between the adjacent stripe-shaped burn-suppressing regions 122. Since the regions 123 are constituted by a part of the base paper 121, they can burn in an ordinary smoking state. Therefore, the regions 123 each act as a non-burn-suppressing region.
- the stripe-shaped burn-suppressing regions 122 each may have a width of 1 to 6 mm in the circumferential direction. The distance between the adjacent burn-suppressing regions 122 may be 2 to 20 mm.
- a non-burn-suppressing region 124 may be provided to the region covering a distance d from the tip 11a of the base paper 121.
- FIG. 2 is a schematic perspective view, partly broken away, showing an example of a cigarette that is wrapped with a cigarette paper having annular band-shaped burn-suppressing regions according to another embodiment of the present invention.
- the cigarette 20 has a similar structure to that of the cigarette 10 shown in FIG. 1 , except for the structure of the burn-suppressing regions in the wrapping paper. Therefore, in FIG. 2 , an identical reference number is assigned to the same element as the constitutional element in FIG. 1 , and the explanation thereof is omitted.
- annular band-shaped burn-suppressing regions 211 are formed on the base paper 121 of the wrapping paper 21 wrapping the tobacco filler 13, defining burn-suppressing regions. These annular band-shaped burn-suppressing regions 211 are formed apart from each other in the longitudinal direction of the tobacco rod 11.
- Non-burn-suppressing regions 212 are formed between the adjacent annular band-shaped burn-suppressing regions 211. Since the non-burn-suppressing regions 212 are constituted by a part of the base paper 121, they can burn in an ordinary smoking state. Therefore, the regions 212 each act as a non-burn-suppressing region, as the regions 123 in FIG. 1 do.
- the annular band-shaped burn-suppressing regions 211 each may have a width of 4 to 7 mm in the longitudinal direction. The distance between the adjacent burn-suppressing regions 211 may be 18 to 25 mm.
- Smoking articles as referred to herein are not particularly limited and can for example be cigarettes, cigarillos or the like. They typically have a generally cylindrical rod shaped configuration and include a charge, roll, or column of smokable material, such as shredded tobacco (e.g. in cut filler form), which is surrounded by a paper wrapper forming a so-called "tobacco rod".
- a cigarette or cigarillo usually also has a cylindrical filter element aligned in end-to-end relationship with the tobacco rod.
- the filter element may, for example, comprise a plug of cellulose acetate tow, and the tow is circumscribed by a wrapper material known as "plug wrap".
- the filter element is attached to one end of the tobacco rod using a circumscribing wrapping material known as "tipping wrapper".
- the filter element wrapped by the tipping wrapper is known as "mouthpiece element”.
- wt.-% is to be understood as weight percent, based on the dry weight of the base paper, unless explicitly otherwise specified. In the present disclosure, all amounts given in wt.-% in a particular embodiment add up to 100 wt.-%. The weight percent are thereby calculated by dividing the mass of each component by the dry mass of the base paper.
- a "low ignition propensity" smoking article is one that has been designed to be less likely than a conventional cigarette to ignite furnishings and equipment, e.g. soft furnishings such as a couch or mattress. Ideally, a low ignition propensity smoking article will continue to burn when freely suspended such as in the holder of an ashtray or when being held in the hand without puffing ("free burn"). The tendency for a cigarette to go out during free burn is referred to as "self-extinguishment”.
- LIP bedding or upholstered furniture
- FASE The likelihood of a smoking article to extinguish while burning in free air (referred to as FASE) may be measured by any suitable method. In the present invention this is done according to ISO 12863:2010.
- TNCO levels as referred to herein stand for tar, nicotine and carbon monoxide levels and can be measured by any suitable method. In the present invention this is done according to ISO 3308:2012.
- the symbol “CU” herein designates the CORESTA air permeability unit that is commonly used in paper specifications by smoking article designers.
- the CORESTA air permeability unit is defined as: "the volumetric flow rate of air in cubic centimeters per minute (cm3/min) passing through a 1 square centimeter (cm2) sample of substrate at an applied pressure difference of 1 kilo-Pascal (kPa).” and are measured according to ISO 6565:2011.
- the number of puffs of a smoking article may be measured by any suitable method. In the present invention this is done according to ISO 3308:2012.
- the diffusion capacity of a wrapping paper is measured in the present invention according to CORESTA Recommended Method No. 77 (CRM No. 77) of April 2014 .
- the present invention relates to a wrapping paper for a smoking article comprising a base paper, wherein the base paper comprises a plurality of burn-suppressing regions that are provided apart from each other, wherein the ratio of diffusion capacity between the burn-suppressing regions and the base paper is in the range of 5% to 35%.
- the wrapping paper is formed of a base paper with burn-suppressing regions provided therein. As the regions of the wrapping paper which are outside the burn-suppressing regions are to be considered as non-burn suppressing regions the latter being the same as the base paper, the present application uses the terms "non-burn suppressing regions" and "base paper” interchangeably.
- the ratio of diffusion capacity between the burn-suppressing regions and the non-burn-suppressing regions, i.e. the base paper is in the range of 10% to 35%, or 15% to 35%, or 5% to 30%, or 10% to 30%, or 15% to 30%, or 10% to 25%, or 15% to 25%.
- the ratio of diffusion capacity between the burn-suppressing regions and the non-burn-suppressing regions is in the range of 9% to 17%. It has been found that the impact on taste is particularly reduced in this range while the wrapping paper still exhibits a good LIP and FASE performance.
- the burn-suppressing regions may be provided on a surface of the base paper or embedded within a matrix of the base paper.
- the plurality of burn-suppressing regions may be provided on a same surface of the base paper.
- one or more of the plurality of burn-suppressing regions may be provided on a first surface of the base paper and the remaining of the plurality of burn-suppressing regions may be provided on a second, opposite surface of the base paper.
- burn-suppressing regions are not further limited and may vary according to the specific requirements of the smoking article.
- the burn-suppressing regions are in a form of stripes. In one embodiment all stripes are parallel to each other. In another embodiment at least two stripes are non-parallel to each other.
- the burn-suppressing regions are in a form of stripes extending in a longitudinal direction of the tobacco rod and being spaced apart from each other in a circumferential direction of the tobacco rod.
- the burn-suppressing regions are in a form of round annular bands extending in a circumferential direction of the tobacco rod and being spaced from each other in a longitudinal direction of the tobacco rod.
- the diffusion capacity of the base paper is 1.0 to 2.0 cm/s, e.g. 1.0 to 1.8 cm/s, or e.g. 1.2 to 1.6 cm/s, or e.g. 1.2 to 2.0 cm/s, or e.g. 1.2 to 1.8 cm/s, or e.g. 1.2 to 1.6 cm/s, or e.g. 1.4 to 2.0 cm/s, or e.g. 1.4 to 1.8 cm/s, or e.g. 1.4 to 1.6 cm/s.
- the diffusion capacity of the burn-suppressing regions is 0.10 to 0.35 cm/s, or e.g. 0.15 to 0.35 cm/s, or e.g. 0.20 to 0.35 cm/s or e.g. 0.10 to 0.30 cm/s, or e.g. 0.15 to 0.30 cm/s, or e.g. 0.20 to 0.30 cm/s, or e.g. 0.10 to 0.25 cm/s, or e.g. 0.15 to 0.25 cm/s, or e.g. 0.20 to 0.25 cm/s.
- These burn-suppressing regions may contain additives that reduce the diffusion capacity of the base paper.
- the additives that may be applied to the wrapper may be any of those used in the art to reduce the ignition propensity of smoking articles.
- the burn-suppressing regions in the wrapping paper contain at least one additive that reduces the diffusion capacity of the base paper.
- the additives are optionally selected from the group consisting of alginates, polyvinyl alcohol, polyvinyl acetates, including partially hydrolyzed derivatives and copolymers, modified and unmodified starches, cellulose derivatives, such as carboxy-methyl cellulose, ethyl-cellulose, hydroxymethyl-cellulose and combinations thereof.
- the additives may further comprise inorganic ions such as phosphates, mono- or divalent metal salts, silicas or mixtures thereof.
- the additives may yet further comprise natural gums, such as guar gum.
- the additives may be applied to the wrapping paper with a liquid carrier, which may be in the form of a solution, suspension, emulsion or a combination thereof.
- the liquid carrier may be aqueous, non-aqueous or a combination thereof and may contain an emulsifying agent depending on the nature of the additives.
- a suspension of additive may be applied within an aqueous carrier.
- the aqueous carrier penetrates the base paper transporting the additive into its matrix. Once the carrier evaporates, the additive is left within the base paper matrix where it can reduce the diffusion capacity either before or during the burning of the smoking article. Once applied to the base paper, the liquid carrier is allowed to evaporate allowing the wrapping paper to dry and for the additive to set within the matrix of the base paper.
- the base paper comprises a fibrous material, a filler material, and one or more burning additives.
- the paper porosity of the base paper is 10 to 60 CU and a total amount of burning additive is 0.1 to 0.7 wt.-% based on the dry weight of the base paper.
- the paper porosity of the base paper is 10 to 50 CU, e.g. 15 to 45 CU. This further increases the puff count of the smoking article.
- the burning additive is included in the base paper in an amount of 0.2 to 0.6 wt.-%, e.g. 0.3 to 0.5 wt.-% based on the dry weight of the base paper. This further increases the puff count of the smoking article.
- the burning additive is selected from the group consisting of citrate salts, e.g. sodium and potassium citrate, acetate salts, e.g. sodium and potassium acetate, phosphate salts, e.g. sodium and potassium phosphate, tartrate salts, e.g. sodium and potassium tartrate, nitrate salts, e.g. sodium and potassium nitrate, or mixtures thereof.

- tartrate salts e.g. sodium and potassium tartrate
- nitrate salts e.g. sodium and potassium nitrate
- the burning additive is not particularly limited, as long as it is suitable for use in a smoking article.
- citrate salts are used.
- the amount of filler in the base paper is 17 to 28 wt.-%, e.g. 20 to 25 wt.-%, based on the dry weight of the base paper. This amount of filler provides an adequate resistance to manufacturing forces to which the wrapping paper is subject to during high speed manufacturing and also allows obtaining a desired opacity of the wrapping paper.
- the filler in the base paper is selected from the group consisting of calcium carbonate, such as precipitated calcium carbonate (PCC) or ground calcium carbonate (GCC), kaolin clay, talc, titanium dioxide, alumina trihydrate, and precipitated silica and silicates (PSS), or mixtures thereof.

- the amount of filler in the base paper is 17 to 23 wt.-%, e.g. 19 to 21 wt.-%, e.g. 20 wt.-%, based on the dry weight of the base paper.
- the balance to 100 wt.-% of the dry weight of the base paper is essentially filler and fibrous material.
- the basis weight of the base paper is 20 to 26 g/m 2 , e.g. 21 to 24 g/m 2 , or e.g. 23 to 25 g/m 2 , e.g. 24 g/m 2 .
- the fibrous material is a cellulosic fibrous material.
- the present invention further relates to a smoking article comprising a wrapping paper as in the embodiments described above and in which the wrapping paper surrounds a charge, roll or column of smokable material to form a tobacco rod.
- the burn-suppressing regions are in a form of stripes extending in a longitudinal direction of the tobacco rod and being spaced apart from each other in a circumferential direction of the tobacco rod.
- the burn-suppressing regions are in a form of round annular bands extending in a circumferential direction of the tobacco rod and being spaced from each other in a longitudinal direction of the tobacco rod.
- the present invention relates to a wrapping paper comprising a plurality of burn-suppressing regions that are provided apart from each other on one surface of the wrapping paper, wherein the ratio of diffusion capacity between the burn-suppressing regions and the non-burn suppressing regions is in the range of 5% to 35%.
- the positive effect of the present invention i.e. the combination of a low ignition propensity without a deterioration of taste properties is due to the specific ratio of diffusion capacity between the burn-suppressing regions and the non-burn suppressing regions that are provided apart from each other at the base paper as laid out above.
