Aerosol-generating article comprising a downstream element comprising a paper material

Abstract

An aerosol-generating article comprises: an aerosol-generating substrate; and a downstream element provided downstream of the aerosol-generating substrate and in axial alignment with the aerosol-generating substrate. The downstream element comprises a plug element. The plug element comprises a cellulosic filtration material. The cellulosic filtration material comprises: a paper material; and an additive coating applied to the paper material. The additive coating comprises at least 5 percent by weight of exogenous lignin on a dry weight basis. An overall content of lignin in the plug element is at least 2 percent by weight of the plug element.
