AI Technical Summary

Technical Problem

In existing heated aerosol generation products, fibrous filter materials such as cellulose acetate tows are non-biodegradable, leading to environmental pollution. Furthermore, alternative materials are insufficient in terms of robustness and filtration efficiency, affecting the consumer experience.

Method used

The rod element, made of regenerated cellulose and treated paper material, includes first and second barrier layers that hold embossed filter material, providing structural support and filtration efficiency, and reducing the release of unwanted compounds such as phenols.

Benefits of technology

This achieves biodegradability of aerosol-generated products, improves filtration efficiency and consumer experience, while reducing environmental pollution and meeting environmental regulations.
