Abstract: A tubular element for an aerosol-generating article is provided, the tubular element including: a tubular body defining a cavity extending from a first end of the tubular body to a second end of the tubular body; a folded end portion forming a first end wall at the first end of the tubular body, the first end wall delimiting an opening for airflow between the cavity and an exterior of the tubular element; and a ventilation zone at a location along the tubular body of the tubular element, the ventilation zone being located between about 5 millimetres and about 15 millimetres from the folded end portion of the tubular element.

Abstract: An aerosol-generating article including a plurality of elements assembled in the form of a rod is provided, the elements including: a first element including an aerosol-generating substrate; and a tubular element positioned upstream or downstream of the first element, the tubular element including: a tubular body defining a cavity extending from a first end of the tubular body to a second end of the tubular body, and a folded end portion forming a first end wall at the first end of the tubular body, the first end wall delimiting an opening for airflow between the cavity and an exterior of the tubular element, the cavity in the tubular element being an empty cavity.
