Insulation Sleeve for Aerosol Generation Device

Abstract

An insulation sleeve for an aerosol generation device, and used therein for a heating assembly therein, includes natural organic fibres. The natural material comprised in the insulation sleeve is easily available and eco-friendly; it also increases the sustainability of the component and devices including it. The cost of manufacturing the insulation sleeve with the natural material is very low.
