Definitions
- the present disclosure relates to the field of devices for heating tobacco without burning it and the subject thereof is a reconstituted plant sheet obtained by means of a high-density papermaking process.
- Reconstituted tobacco is more suitable for these heating devices, since it makes it possible to generate a large amount of aerosol having advantageous organoleptic properties.
