Abstract (en)
[origin: EP4140324A1] A tobacco rod, an aerosol-generating article including the same, and an aerosol generation device used with the aerosol-generating article are provided. The tobacco rod according to some embodiments of the present disclosure may include a first filter segment, a second filter segment, and a cavity segment which is formed by the first filter segment and the second filter segment and filled with a tobacco material. Here, at least one of the first filter segment and the second filter segment may include a grease-resistant or water-resistant paper material. Accordingly, a problem that vapor production is decreased due to moisture absorption from components of smoke can be addressed, and a heat-resistant tobacco rod can be manufactured.
