High-Density Reconstituted Plant Sheet

Abstract

The invention relates to a reconstituted plant sheet suitable for devices for heating tobacco without burning it, said reconstituted plant sheet having a high density.

1 . Reconstituted plant sheet comprising:
 a fibrous support comprising refined plant fibers,   an aerosol-generating agent, and   a plant extract,   characterized in that   the density of the reconstituted plant sheet is greater than or equal to 0.6 g/cm 3 , the total content by weight of solids of aerosol-generating agent is between 10% and 29%.   
     
     
         2 . Reconstituted plant sheet according to  claim 1 , the density of which is between 0.62 g/cm 3  and 1.50 g/cm 3 . 
     
     
         3 . Reconstituted plant sheet according to  claim 1 , in which the plant is the tobacco plant. 
     
     
         4 . Reconstituted plant sheet according to  claim 1 , in which the total content by weight of solids of the plant extract is between 20% and 45%. 
     
     
         5 . Reconstituted plant sheet according to  claim 1 , in which the sum of the total content by weight of solids of plant extract and of the total content by weight of solids of aerosol-generating agent is between 40% and 70%. 
     
     
         6 . Reconstituted plant sheet according to  claim 1 , the thickness of which is between 100 μm and 450 μm. 
     
     
         7 . Reconstituted plant sheet according to  claim 1 , the basis weight of which is between 60 g/m 2  and 300 g/m 2 . 
     
     
         8 . Reconstituted plant sheet according to  claim 1 , in which the aerosol-generating agent is sorbitol, glycerol, propylene glycol, triethylene glycol, lactic acid, glycerol diacetate, glyceryl triacetate, triethyl citrate, isopropyl myristate, or a mixture thereof. 
     
     
         9 . Process for producing a reconstituted plant sheet as defined in  claim 1 , comprising the following steps:
 a) passing the refined plant fibers through a papermaking machine so as to constitute a fibrous support,   b) bringing an aerosol-generating agent and a plant extract into contact with the fibrous support so as to obtain a wet reconstituted plant sheet, and   c) drying the wet reconstituted plant sheet.   
     
     
         10 . A heat but not burn device comprising reconstituted plant sheet as defined in  claim 1 , placed in association with in a heating device.
