Description

Components for aerosol supply items The present invention relates to a component for an aerosol-providing article. Popular aerosol-generating articles may have a substantially cylindrical rod-shaped structure and may include a filler, roll, or column of smokeable material, such as shredded tobacco (e.g., in the form of a cut filler), surrounded by a paper wrapper, thereby forming a rod of aerosolizable material. Typically, the aerosol-generating article has a filter element aligned with the rod of aerosolizable material in an end-to-end relationship. Generally, the filter element comprises a rod of plasticized cellulose acetate tow surrounded by a paper material known as a plug wrap, and the filter is attached to one end of the rod of aerosolizable material using a surrounding wrapping material known as a tipping material. In one aspect of the present invention, a component for an aerosol-providing article is provided.
