Description

Aerosol generating composition Technical field The present disclosure relates to an aerosol-generating composition, a method for manufacturing an aerosol-generating material and articles comprising aerosol generating material. Background Aerosol provision products produce an aerosol during use, which is inhaled by a user. For example, tobacco heating devices heat an aerosol generating material such as tobacco to form an aerosol by heating, but not burning, the substrate. Such an aerosol provision product commonly includes an aerosol-generating section or region, which generate an aerosol in use, and a mouthpiece through which the aerosol passes to reach the user’s mouth. There is a need however to improve such aerosol generating materials, both in terms of, for example, their flavour delivery, ease of manufacture and their format in the delivery device. Summary According to a first aspect of the invention, there is provided an aerosol generating composition comprising one or more extruded strands of aerosol-generating material, the one or more extruded strands of aerosol-generating material comprising a length, a width and a height and wherein the width and height are substantially the same and the length is greater than the height or width. In some embodiments, the one or more extruded strands has a cross-section with the shape selected from a group consisting of: circular, semi-circular, crescent, Y-shaped and star. In some embodiments, the one or more extruded strands has a cross-section which is substantially non-rectangular, non-square or non-cuboidal. In some embodiments, each of the one or more extruded strands is in the form of a continuous strand. In some embodiments, the aerosol generating composition comprises two or more extruded strands and at least two of the two or more extruded strands are substantially the same length. In some embodiments, each of the one or more extruded strands has substantially the same width across its length, and optionally substantially the same cross section along its length. In some embodiments, the one or more extruded strands has a tensile strength of at least 4 N/15 mm. In some embodiments, one or more of the extruded strands can stretch to at least about 104% of its length before breaking. In some embodiments, the aerosol-generating material comprises water. In some embodiments, the aerosol-generating material comprises a water content of up to about 40% by weight. In some embodiments, the aerosol generating material comprises botanical material. In some embodiments, the aerosol generating material comprises a botanical material content of about 50 to about 80% by weight. In some embodiments, the aerosol-generating material has a density of about from about 0.5 g/cm3 to about 1 g/cm3. In some embodiments, the aerosol generating composition comprises botanical material in the form of particles. In some embodiments, the particles have a D90 of about 70 to about 600 pm. According to a second aspect of the invention, there is provided an article for use with a non-combustible aerosol-provision system comprising the aerosol generating composition. In some embodiments, the one or more extruded strands are aligned lengthways with a longitudinal axis of the article. The extruded strands maybe in parallel alignment with a longitudinal axis of the article. In some embodiments, the method comprises: forming a mixture; extruding the mixture through a die to form an extruded aerosol-generating material; and cutting the aerosol-generating material to form the one or more extruded strands. In some embodiments, the method does not comprise shredding the aerosol generating composition. In some embodiments, the extruded aerosol-generating material is dried at a temperature not exceeding too °C. According to a fourth aspect of the invention, there is provided an aerosol generating composition produced by the process.
