Description

Material for use as a component for aerosol delivery items The present invention relates to a material for use as 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 material for use as a component of an aerosol-providing article is provided. The material comprises a plurality of substrate sheets arranged in layers with respect to each other, and at least one of the plurality of substrate sheets is formed from either a plurality of regenerated cellulose fibers or paper. In some embodiments, the total weight of the plurality of substrate sheets may be in the range of 40 gsm to 90 gsm. In some embodiments, each of the plurality of substrate sheets may have the same weight in grams per square meter.
