High-Density Reconstituted Plant Sheet

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.
