Definitions

  • the present invention is directed to an aerosol generating article as for example a cigarette.
  • the present application is especially directed to a tipping wrapper for aerosol generating articles as for example cigarettes.
  • Cigarettes known from the state of the art comprise usually several components as for example a filter, a cigarette body and a so-called tipping wrapper, which is usually at least partially wrapped around the filter.
  • tipping wrapper also often referred to as "tipping paper” in the art, has the function to connect the mouthpiece rod and the tobacco rod, but it is furthermore known from the state of the art, that decoration such as printing, hot foiled stamping or embossing is added to this tipping wrapper.
  • decoration such as printing, hot foiled stamping or embossing is added to this tipping wrapper.
  • shiny appearance especially high glossiness
  • tipping wrapper has been expected to enhance the attractiveness of the product.
  • a known technique in this field is silver ink printing to obtain such shiny appearance but, in this case, an additional printing process is required.
  • the shiny appearance can be obtained by calandraring a paper containing more than 10 % Kaolin. In this case the problem arises, that ink abrasion from the paper surface after printing may arise.
  • the tipping wrapper should be non-combustible (it should comprise smol-dering resistance) because it is a connecting part of the mouthpiece and the tobacco rod. To assure sufficient non-combustibility some non-combustible tipping wrapper was developed which a certain amount of non-combustible filler.
  • titanium dioxide As such a filler, titanium dioxide has been widely used. This material has the advantage of high opacity (delivers higher opacity to the paper) and non-combustibility. However, in some countries this material is prohibited because of health concerns.
  • a tipping paper which contains nanofibers of organic polymers.
  • the nanofibers could additionally contain inorganic compounds.
  • a combination of polycaprolactone and CaCOs was found to be suitable.
  • tipping wrapper should have a good lip feeling during smoking. Consumers generally like better lip release feelings, which means, that a cigarette should not be stuck on the lip after puffing. For this reason it's common to add lip release varnish on the surface of the tipping wrapper to avoid that it gets stuck on the mouth of the consumer.
  • a tipping wrapper according to the invention for an aerosol generating article for example a cigarette has a base layer with a porosity of less than 1,5 C.U., wherein the base layer contains at least one filler material and wherein the tipping wrapper further comprises a surface, especially a pigmented surface, which is pigmented with a pigment component, which contains CaCOs and at least a second component serving as a non-combustible filer, wherein the pigment component has a grammage of at least 2,0 g/m 2 , and wherein the pigmented surface has a surface smoothness of at least 400 s.
  • the tipping wrapper is a tipping paper.
  • the material of the tipping wrapper is paper.
  • the here described tipping wrapper fulfills general tipping wrapper requirements as for example to sufficient ink fixability, to non-combustibility and machine runability.
  • the tipping wrapper according to the invention comprises a shiny appearance and an improved lip feeling.
  • the filler material is chosen from a group of materials which contains Kaolin, CaCOs, talc and Al(OH) 3 (aluminum hydroxide).
  • one of these materials can be contained in the filler materials, two, several, or all those materials. Also an arbitrary combination of the materials can be contained as for example Kaolin and talc or CaCOs and Al(OH) 3 .
  • the above-mentioned smoothness is preferably measured with the Bekk method.
  • the Bekk smoothness testing is an informative technique for determining the smoothness of a sample.
  • the smoothness or the roughness is a substantial surface property of papers, cartons or cardboard, coated sheets or the like.
  • the quality of the surface structure has a great influence on the printability and any form of coating.
  • the Bekk smoothness measurement is a method established in the paper industry based on airflow. This slower the air flows between the paper surface and the ideal plain, the higher the smoothness, expressed in Bekk smoothness seconds. In a preferred method, a representative paper of approximately 10 cm 2 can be tested in the Bekk method.
  • the above-mentioned glossiness refers to the specular gloss of paper.
  • specular gloss testing is an informative technique for determining the glossiness of a sample.
  • the glossiness is a substantial surface property of papers, cartons or cardboard, coated or laminated sheets or the like.
  • the quality of the surface glossiness has a great influence on the appearance.
  • the glossiness measurement is a method established in the paper industry based on specular reflection.
  • specular gloss expressed as a percentage, of the luminous flux reflected by the sample surface into a specified aperture at the angle of specular reflection to that from a standard specularly reflecting surface under the same conditions.
  • the light incident on the test piece surface at an angle of 60 degrees.
  • the second component is chosen from a group of components which contains Kaolin, talc or aluminum hydroxide Al(OH) 3 . Also the second component may contain more than one of these components. Also the second component may contain a certain selection of these components as Kaolin and talc or talc, Kaolin and aluminum hydroxide Al(OH) 3 .
  • the base layer is a base paper.
  • the above-mentioned pigmented surface can also be referred to as a printing surface.
  • the pigmented surface is attached to the base layer.
  • the Unit C.U. is understood as so called Coresta Unit which is defined by the volumetric flow rate of air (in the unit cm 3 /min) passing through a 1 cm 2 sample of a substrate at an applied pressure difference of 1 kPa.
  • the pigmented layer may comprise a printing.
  • the pigmentation layer serves for improving the brightness of the tipping wrapper.
  • the smoothness of the pigmented surface is at least 500 s (measured with the Bekk method).
  • the base layer and the pigmented surface build a double layer structure.
  • these two layers can be attached to each other.
  • the filler material of the base layer is chosen of or contains a material chosen from a group of materials which contains Kaolin, CaCOs, talc and aluminum hydroxide (Al(OH) 3 ). Preferably, more of these materials are comprised in the filler material of the base layer.
  • the basis weight of the tipping wrapper is greater than 40 g/m 2 , preferred greater than 45 g/m 2 . In another preferred embodiment the basis weight of the tipping wrapper is smaller than 60 g/m 2 , preferably smaller than 55 g/m 2 . Those basis weights have been proven to be in a preferred range especially for machine run ability on manufacturing machines.
  • a thickness of the tipping wrapper is greater than 30 ⁇ m, preferably greater than 35 ⁇ m.
  • the thickness of the tipping wrapper is smaller than 55 ⁇ m, preferably smaller than 50 ⁇ m.
  • the thickness along the tipping wrapper surface has a deviation of less than 20 % preferably of less than 10 %.
  • a paper density of the tipping wrapper is greater than 1,1 g/cm 3 , preferably greater than 1,15 g/cm 3 .
  • a paper density of the tipping wrapper is smaller than 1,3 g/cm 3 , preferably smaller than 1,25 g/cm 3 .
  • this feature enhances the machine run ability on a cigarette making machine.
  • a smoothness of the tipping wrapper is greater than 500 s, preferably greater than 600 s and preferably greater than 700 s.
  • a smoothness of the tipping wrapper is smaller than 2500 s, preferably smaller than 2000 s.
  • a glossiness of the tipping wrapper is greater than 10 %, preferably greater than 15 % and preferably greater than 20 %.
  • a glossiness of the tipping wrapper is smaller than 35 %, preferably smaller than 30 %.
  • a pigment component contains the CaCOs (Calcium carbonate) and Kaolin in a ration which is between 3:7 and 7:3, preferably between 4:6 and 7:3 and most preferably between 5:5 and 6:4.
  • the amount of the pigmentation is higher than 2 g/m 2 , preferably higher than 3 g/m 2 , preferably higher than 4 g/m 2 and preferably higher than 5 g/m 2 .
  • the tipping wrapper is free of titanium dioxide (TiO 2 ). In this case, possible health risks as considered in some countries are avoided.
  • the pigmented surface is based on a coating solution, which comprises water, a binder component and the pigmentation component.
  • a coating solution which comprises water, a binder component and the pigmentation component.
  • other components may be comprised.
