Aerosol-Generating Substrate Comprising An Aerosol-Generating Film
Patent No. EP4403049 (titled "Aerosol-Generating Substrate Comprising An Aerosol-Generating Film") was filed by Philip Morris on Mar 18, 2020. The application was issued on Jan 14, 2026.
Patent Summary
An aerosol-generating article comprises a rod of aerosol-generating substrate containing a substantially tobacco-free aerosol-generating film. The film consists of at least 25% by weight of a polyhydric alcohol (e.g., propylene glycol, glycerin) and at least 10% by weight of a cellulose-based film-forming agent (e.g., HPMC). The film is configured such that its bulk density is at least 100 mg per cubic centimetre of the substrate rod. The film may be configured as stacked layers, strips, shreds, or hollow beads to maximize exposed surface area for efficient aerosol release upon heating (180°C to 250°C). The article may be used in an electrically operated system featuring a heater element, such as a blade, pin, or inductive susceptor.
