AI Technical Summary

⚠Technical Problem

Existing aerosol-generating substrates, particularly cylindrical rods of plant material, face inefficiencies in aerosol generation due to non-uniform heating and high density, leading to waste and increased resistance to draw, limiting flexibility in design and manufacturing speed.

⚗Method used

Aerosol-generating substrates comprising at least 10% aerosol former by weight, with a diameter to thickness ratio between 2 and 50, allowing for thin, wide elements that enhance surface area, reduce thermal inertia, and facilitate efficient heating, while maintaining low resistance to draw.

🎯Benefits of technology

The solution improves aerosol generation efficiency, reduces thermal inertia, and allows for flexible design adaptations, ensuring uniform heating and reduced manufacturing challenges, while maintaining low resistance to draw.

Abstract

An aerosol-generating substrate is for use in an aerosol-generating article or system is provided. The aerosol-generating substrate comprises at least 10 percent by weight of an aerosol former on a dry weight basis. The aerosol-generating substrate is in the form of at least one aerosol-generating element. The at least one aerosol-generating element has a first planar surface and a second opposed planar surface. The at least one aerosol-generating element has a diameter and a thickness. The ratio of the diameter of the at least one aerosol-generating element to the thickness of the at least one aerosol-generating element is between 2 and 50. An aerosol-generating article comprising the aerosol-generating substrate is also provided.
