Title:
MULTI-LAYER CIGARETTE PAPER FOR ELECTROMAGNETIC INDUCTION
Document Type and Number:
WIPO Patent Application WO/2023/050854
Kind Code:
A1
Abstract:
The present invention provides a multi-layer cigarette paper for electromagnetic induction. The multi-layer cigarette paper for electromagnetic induction comprises an outer wrapping layer, a heat insulation layer, and a heating layer which are successively stacked, the heating layer is arranged on the heat insulation layer, and the heating layer is used for heating, under the induction of an alternating magnetic field, an aerosol-generating substrate wrapped in the heating layer to generate an aerosol. According to the present invention, the heat insulation layer and the heating layer are successively provided in the cigarette paper, so that heat generated by the heating layer is restrained inside the heat insulation layer under the obstruction of the heat insulation layer and is gradually transferred from the periphery of the aerosol-generating substrate to the center of the aerosol-generating substrate, and thus the aerosol-generating substrate is fully and uniformly heated.
