Stable wrapper for aerosol generating article

Abstract

A wrapper for aerosol generating articles. The wrapper has a high paper density and may be utilized with an aerosol generating substrate. An aerosol generating article includes an aerosol generating substrate comprising nicotine, and a wrapper disposed about the aerosol generating substrate. The wrapper includes a paper layer having a thickness/grammage of about 1.2 micrometers/gsm or less.

1 . A heat-not-burn aerosol-generating article comprising:
 an aerosol generating substrate comprising nicotine and at least about 10% aerosol former comprising glycerine;   a mouthpiece segment comprising a plug of cellulose acetate;   a hollow cellulose acetate tube between the mouthpiece segment and the aerosol generating substrate;   a hollow tubular segment separating the hollow cellulose acetate tube from the mouthpiece segment, the hollow tubular segment comprises a ventilation zone;   a wrapper disposed about and in contact with the aerosol generating substrate, the wrapper comprises a paper layer having a thickness/grammage of about 1.0 to about 1.2 micrometers/gsm or less; and   a second paper layer disposed about the wrapper and joining the aerosol generating substrate, hollow cellulose acetate tube, hollow tubular segment, and mouthpiece segment together.   
     
     
         2 . The heat-not-burn aerosol-generating article according to  claim 1 , wherein the wrapper and the second paper layer are coextensive. 
     
     
         3 . The heat-not-burn aerosol-generating article according to  claim 1 , wherein the aerosol generating substrate comprises tobacco and from about 10% to about 20% glycerine. 
     
     
         4 . The heat-not-burn aerosol-generating article according to  claim 3 , wherein the aerosol generating substrate comprises homogenized tobacco. 
     
     
         5 . The heat-not-burn aerosol-generating article according to  claim 1 , wherein the wrapper has a permeability in a range from about 1 to about 10 CORESTA units. 
     
     
         6 . The heat-not-burn aerosol-generating article according to  claim 1 , wherein the wrapper is formed of at least 95% cellulosic material. 
     
     
         7 . The heat-not-burn aerosol-generating article according to  claim 1 , wherein the second paper layer is formed of at least 95% cellulosic material. 
     
     
         8 . A heat-not-burn system comprising:
 a heat-not-burn aerosol-generating article comprising:
 an aerosol generating substrate comprising tobacco and at least about 10% aerosol former comprising glycerine; 
 a mouthpiece segment comprising a plug of cellulose acetate; 
 a hollow cellulose acetate tube between the mouthpiece segment and the aerosol generating substrate; 
 a hollow tubular segment separating the hollow cellulose acetate tube from the mouthpiece segment, the hollow tubular segment comprises a ventilation zone; 
 a wrapper disposed about and in contact with the aerosol generating substrate, the wrapper comprises a paper layer having a thickness/grammage of about 1.2 micrometers/gsm or less; and 
 a second paper layer disposed about the wrapper and joining the aerosol generating substrate, hollow cellulose acetate tube, hollow tubular segment, and mouthpiece segment together; 
   an aerosol-generating device comprising a receptacle for receiving the heat-not-burn aerosol-generating article and a heating element configured to heat the aerosol generating substrate when the aerosol generating substrate is received in the receptacle.   
     
     
         9 . The heat-not-burn system according to  claim 8 , wherein the heating element is an electrically resistive heating element. 
     
     
         10 . The heat-not-burn system according to  claim 8 , wherein the aerosol-generating device comprises a power supply and control electronics to control heating of the heating element. 
     
     
         11 . The heat-not-burn system according to  claim 8 , wherein the wrapper and the second paper layer are coextensive. 
     
     
         12 . The heat-not-burn system according to  claim 8 , wherein the aerosol generating substrate comprises tobacco and from about 10% to about 20% glycerine. 
     
     
         13 . The heat-not-burn system according to  claim 8 , wherein the aerosol generating substrate comprises homogenized tobacco. 
     
     
         14 . The heat-not-burn system according to  claim 8 , wherein the wrapper has a permeability in a range from about 1 to about 10 CORESTA units. 
     
     
         15 . The heat-not-burn system according to  claim 8 , wherein the wrapper is formed of at least 95% cellulosic material. 
     
     
         16 . The heat-not-burn system according to  claim 8 , wherein the second paper layer is formed of at least 95% cellulosic material.
