A cartridge for a handheld aerosol-generating system, comprising: a cartridge body comprising an outer wall, an inner airflow tube within an outer body, and a sealing element that seals the inner airflow tube, such that that air cannot pass completely through the inner airflow tube from one end to an opposite end, wherein the sealing element is integrally moulded with the airflow tube and the inner airflow tube is spaced from the outer wall; and a reservoir of aerosol-forming substrate between the outer wall and the inner airflow tube; wherein the outer wall and inner airflow tube are connected to one another through one or more ribs extending between the outer wall and inner airflow tube, and wherein the outer wall, inner airflow tube and one or more ribs are integrally moulded.
