Definitions

  • This invention relates in general to tobacco processing and, more particularly, to coated reconstituted tobacco sheet.
  • Tobacco sheet may be made by depositing a thin layer of an aqueous or other suspension of finely-divided tobacco and a suitable binder on a flat surface. The thin layer is then dried and removed from the surface as tobacco sheet.
  • tobacco sheet If such tobacco sheet is used as a cigar wrapper, it should exhibit all the features of a natural tobacco leaf cigar wrapper such as good color and sheen, a natural feel, no stickiness in the mouth, no unusual or bitter flavor characteristics, good burn aroma and taste, and a good burn rate, as well as water resistance.
  • tobacco sheet yields a better performance than natural leaf on cigarmaking machines because it has more uniform physical characteristics than do varied natural tobacco leaves, heretofore some tobacco sheet has lacked the aforementioned desired properties.
  • the invention relates to coating manufactured tobacco sheets with a thin layer of protective material on either one or both sides. It may be used on sheets made by a paper-making process, a process where dust is adhered to a sticky film or where dust is mixed with a binder. When the coating is hydrophobic there is a marked increase in resistance to moisture penetration. When coated on both sides, the sheet is waterproof.
  • a coating must have more than useful physical properties. It must not be noxious or toxic in the amounts used; it must have an acceptable taste and appearance and not detract from the tobacco character of a smoking article. Moreover, the coating material and method must be easy and practical to use with delicate tobacco material.
  • the coating is preferably used on the surface of the sheet which is outermost on the smoking article. Both sides of the sheet may be coated when protection against chewing a desired. Also, several successive layers of coating material may be appplied to the sheet, and in particular to the area at the mouth end of a smoking article. Coating may be applied in the course of sheet manufacture or on the finished smoking article.
  • the invention particularly concerns making a moisture resistant tobacco product and includes or comprises forming a sheet of tobacco by mixing a major proportion by weight of finely divided tobacco With a minor proportion by weight of water soluble adhesive, such as a 3,185,162 Patented May 25, 1965 ice cellulose ether, e.g., ethyl hydroxyethyl cellulose, in aqueous solution and drying the sheet so formed. Thereafter the improvement consists of coating the surface of the dried sheet witha solution of ethyl cellulose and iinally drying the coating to produce a thin, flexible surface coating which protects the water soluble adhesive and the tobacco from attack and degradation by external moisture and is compatible with the smoking quality of the tobacco product.
  • water soluble adhesive such as a 3,185,162 Patented May 25, 1965 ice cellulose ether, e.g., ethyl hydroxyethyl cellulose
  • Example 0.5 part locust beam gum is added slowly, with agitation, to a 2.5% suspension of 1 part of highly refined sulfite pulp in water and agitation is continued until solution is complete.
  • To the resulting dispersion is added, with stirring, 0.75 part diethylene glycol humectant, 0.5 part dialdehyde starch wet strength agent (as a 10% solution), 0.7 part diatomaceous earth and 6 parts tobacco dust (screen through mesh) which has been prewetted with water (1 part tobacco to 2 parts Water).
  • 0.5 part ethyl hydroxyethyl cellulose adhesive are blended in carefully and the total solids adjusted to 10%.
  • the resulting dispersion is cast on a moving stainless steel belt. The sheet on the belt is dried and then coated with an alcoholic solution of ethyl cellulose and the coating dried.
  • a hydrophobic coating on the sheet which may be used is ethyl-cellulose. This may be applied in either an alcoholic solution or as an aqueous emulsion.
