Abstract

An aerosol-generating article (10) for producing an inhalable aerosol upon heating, the aerosol-generating article (10) comprising: a rod (12) of aerosol-generating substrate; a hollow tubular segment (16) at a location downstream of the rod, the hollow tubular segment (16) being in longitudinal alignment with the rod (12), wherein the hollow tubular segment (16) defines a cavity extending all the way from an upstream end of the hollow tubular segment (16) to a downstream end of the hollow tubular segment (16), wherein the hollow tubular segment (16) has a length of at least about 10 millimetres and less than about 25 millimetres; a ventilation zone (26) at a location along the hollow tubular segment (16) less than 45 millimetres from an upstream end of the aerosol-generating article (10); and a mouthpiece segment (18) at a location downstream of the hollow tubular segment (16), the mouthpiece segment (18) comprising a plug of filtration material; wherein the hollow tubular segment (16) comprises a tube formed from a polymeric material or a cellulosic material, the aerosol-generating article (10) further comprising a wrapper circumscribing the rod (12), the tube and the mouthpiece segment (18); wherein a ratio between a weight of the hollow tubular segment (16) and a volume of the internal cavity defined by the hollow tubular segment (16) is less than 1 milligram/cubic millimetres; and wherein the rod (12) of aerosol-generating substrate comprises at least an aerosol former, the rod (12) of aerosol-generating substrate having an aerosol former content of at least about 10 percent on a dry weight basis.
