Definitions

  • aerosol generating articles that include a wrapper described herein may reduce wetting, absorption of water, aerosol formers, or grease in the smoke or aerosol passing through the aerosol generating article.
  • swelling, visible staining and physical weakening of the wrapper portion of the aerosol generating article may be reduced even when a high level of aerosol former is included in the aerosol generating substrate.
  • the aerosol generating article provides a visually and mechanically stable wrapped aerosol generating substrate that avoids swelling. This is particularly useful for heat-not-burn aerosol generating articles that may be inserted into heating device.
  • the aerosol generating article wrapper resists burning if proximate a heating element, thus inductive heating elements may be incorporated throughout the aerosol generating substrate.
  • viscosifying agent refers to a compound that, when added homogeneously into a 25°C, 50% wt water/50% wt glycerine mixture, in an amount of 0.3% wt., increases the viscosity without leading to the formation of a gel, the mixture staying or remaining fluid.
  • Grease penetration is reported according to test method Tappi 559cm-02, classical method 2002. This test method determines the grease penetrability of paper or the wrapper. This test method measures the level of penetration by dropping a mixture of castor oil and solvent onto it. These mixtures are a set of 10 kits, which are prepared with castor oil, n-heptane and toluene as described in following table. The total volume of one kit is 10ml.
  • the sample is placed on a dark surface, testing side upwards.
  • a 25mI drop is deposited onto the paper with a micropipette fixed at a height of 13mm above the sample. After 15 seconds, the surplus is cleaned and immediately after the paper surface is visually examined to check if dark spots appear. Then the paper is removed to carefully check if there are drops on the dark surface. The results are reported as follows:
  • the present disclosure relates to a wrapper used in aerosol generating articles, wherein the wrapper comprises a paper layer having a low grease penetration or grease spotting and may be utilized with an aerosol generating substrate.
  • the wrapper comprises a paper layer having a low grease penetration or grease spotting and may be utilized with an aerosol generating substrate.
  • an aerosol generating article comprising an aerosol generating substrate comprising nicotine, and a wrapper disposed about the aerosol generating substrate.
  • a paper layer has a negative result for all ten kit oil samples of method Tappi 559cm-02, classical method 2002.
  • the wrapper described herein may reduce and prevent formation of spots on an aerosol generating article that are visible to a consumer. It has been observed that spots can appear on an aerosol generating article upon storage in a humid environment or during consumption. The spots can be caused by absorption of water or aerosol former, including any coloured substances that are suspended or dissolved, into the web of cellulosic fibers that constitutes the wrapper. Without being bound by any theory, the water or aerosol former interacts with the cellulosic fibers of the paper and alters the organization of the fibers resulting in a local change in the optical properties, such as brightness, color, and opacity, and mechanical properties, such as tensile strength, permeability of the wrapper.
  • the wrapper described herein, is disposed about an aerosol generating substrate.
  • the wrapper can reduce the absorption of aerosol former compounds and water onto the wrapper as air is drawn through the heated aerosol generating article.
