Definitions

  • Smoking articles such as cigarettes or little cigars, are conventionally made by wrapping a column of tobacco in a wrapping material, made of cigarette paper or homogenized tobacco.
  • the smoking article usually includes a filter or a tip through which the article is smoked. Filters are attached to smoking articles using a tipping paper that is glued to the wrapping paper. When the article is smoked, mainstream smoke is generated that is inhaled through the filter.
  • Mainstream smoke can contain numerous components that provide the smoking article with a particular taste, which encompasses the sensations detected not only by one's taste, but also by one's sense of smell.
  • the wrapping material when made of cigarette paper, should have a white and“clean” look.
  • the wrapping material should also be made from materials and have a porosity that generates a mainstream smoke having a sufficient combustibility and desired taste for the user.
  • a wrapping material should produce a cohesive ash that has a white appearance.
  • wrapping cigarette papers were typically formed from pulp fibers, such as wood or flax fibers, combined with filler particles. Although wrapping cigarette papers can be produced having a white color, such wrapping papers produce a “papery” taste. Wrapping homogenized tobacco materials, on the other hand, were typically made of processed tobacco by-products in an amount greater than 50% and could not achieve satisfying ash appearance or combustibility.

Abstract

L'invention concerne un matériau d'enveloppe qui contient d'environ 10 % à environ 60 % d'un matériau de tabac. Le matériau de tabac présente une taille de particule relativement importante. Par exemple, le matériau de tabac peut présenter une distribution granulométrique de sorte que plus de 80 % des particules de tabac et des fibres présentent une dimension maximale supérieure à environ 0,025 pouce. Le matériau de tabac est combiné à des fibres de pâte à papier blanchie et à une charge, et est formé sous la forme d'une bande au moyen d'un procédé de fabrication de papier. Le matériau d'enveloppe présente un aspect naturel distinct et un goût de papier moins présent par rapport aux papiers à cigarettes classiques. Le matériau d'enveloppe présente un aspect plus clair et plus blanc que les enveloppes de tabac reconstituées classiques et produit une fumée plus homogène présentant un meilleur aspect de cendre.
