Abstract (en)
[origin: EP4193852A1] The present invention is in the technical field of heated cigarettes and in particular relates to a double-layer heated cigarette, and a preparation method and use thereof. The heated cigarette includes an empty tube (2) and an aesthetic paper layer (3) wrapped on the outer layer of the empty tube (2), an end of the empty tube (3) far away from the lip being sealed with a sealing piece (1), and a lateral end of the sealing piece (1) being wrapped by the aesthetic paper layer (3). In the present invention, the aesthetic paper layer is wrapped on the outer layer of the empty tube and the aesthetic paper layer wraps the lateral end of the sealing piece, at the moment, the lateral end of a sealing film/sealing sleeve is not exposed to the outside, which prevents the sealing film/sealing sleeve from falling off the empty tube when the lateral end of the sealing film/sealing sleeve is forced during transport or filling of the cigarette. In addition, the cigarette empty tube is generally a stiffer paper tube and cannot be printed with a pattern. After the outer layer of the empty tube is wrapped with the aesthetic paper layer, the pattern is easily printed and the cigarette becomes more aesthetic.
