High-Density Multilayer Reconstituted Plant Sheet

1 . Reconstituted plant sheet comprising:

two fibrous supports, each fibrous support comprising refined plant fibers and a plant extract,

a plant extract composition between the two fibrous supports, and

an aerosol-generating agent,

characterized in that the density of the reconstituted plant sheet is greater than or equal to 0.60 g/cm 3 .

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 , wherein the plant is the tobacco plant.

4 . Reconstituted plant sheet according to claim 1 , wherein the total content by weight of solids of aerosol-generating agent is between 10% and 30%.

5 . Reconstituted plant sheet according to claim 1 , wherein the total content by weight of solids of the plant extract is between 30% and 60%.

6 . Reconstituted plant sheet according to claim 1 , wherein the sum of the total content by weight of solids of plant extract and the total content by weight of solids of aerosol-generating agent is between 40% and 80%.

7 . Reconstituted plant sheet according to claim 1 , the thickness of which is between 250 μm and 1050 μm.

8 . Reconstituted plant sheet according to claim 1 , the basis weight of which is greater than 200 g/m 2 .

9 . Reconstituted plant sheet according to claim 1 , wherein the aerosol-generating agent is chosen from sorbitol, glycerol, propylene glycol, triethylene glycol, erythritol, propanediol, lactic acid, benzyl benzoate, glyceryl diacetate, glyceryl triacetate, triethyl citrate, isopropyl myristate, and mixtures thereof.

10 . Reconstituted plant sheet according to claim 1 which has been calendered.

11 . 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 produce a base web,

b) bringing a plant extract into contact on the base web to obtain a fibrous support, and

c) bringing a plant extract composition into contact between two fibrous supports so as to obtain the wet reconstituted plant sheet, and

d) drying the wet reconstituted plant sheet to produce the reconstituted plant sheet,

wherein an aerosol-generating agent is incorporated during step b) and/or during step c).

12 . Process for producing a reconstituted plant sheet as defined in claim 11 , wherein the reconstituted plant sheet produced during drying step d) of the process for producing a reconstituted plant sheet undergoes a calendering step.

13 . Consumable for a device for heating tobacco without burning it, comprising a reconstituted plant sheet as defined in claim 1 .

14 . Non-therapeutic use of a reconstituted plant sheet as defined in claim 1 wherein the reconstituted plant sheet is combined with a heating device.

15 . Reconstituted plant sheet as defined in claim 1 for use thereof in a heating device for therapeutic purposes, the plant being chosen from medicinal plants.
