Description

BACKGROUND Technical Field The present disclosure relates to a field of the aerosol-generating product, and more particularly to a heat-not-burn aerosol-generating product and manufacturing method thereof. Related Art At present, heat-not-burn and other new non-tobacco and tobacco products are the developing trend. However, the manufacturing method of the heat-not-burn non-tobacco and tobacco products on the market is complex. The products which are needed more manufacturing devices to manufacture consume quite a lot of manpower and financial resources. Most aerosol-generating article are adopted the shapes of filament, sheet or granule so that the suction effect is bad. For example, the suction resistance of the aerosol-generating article is larger or smaller and the generating aerosol volume is small, when a smoker use a heater to heat the heat-not-burn product.
