Aerosol-generating articles are known in the art, in which an aerosol-generating substrate (such as a tobacco-containing substrate) is heated rather than combusted. Generally, in such heated smoking articles, an aerosol is generated by transferring heat from a heat source to an aerosol-generating substrate.
In the prior art, aerosol-generating articles are generally filled with only a single-density aerosol-forming substrate, and when the volume of the aerosol-generating article is fixed, the higher the filling quality of the aerosol-forming substrate is, the more pumping substances are provided, and the larger the aerosol release amount is; however, since the aerosol-forming substrate has a single density, the higher the filling quality of the aerosol-forming substrate, the lower the void ratio inside the aerosol-forming substrate, the poorer the temperature returning capability of the aerosol-forming substrate in the aerosol-generating product, the unstable heating of the aerosol-forming substrate, the effect of releasing the aerosol, and the higher the density, the waste of the aerosol-forming substrate.
However, when the filling quality of the aerosol-forming substrate is lower, the effective components of the aerosol-forming substrate can be heated and evaporated well although the temperature tempering capability of the inside of the aerosol-forming product is good, the supply amount of the aerosol is smaller, and the effect of releasing the aerosol and the suction effect are affected.

The following description contains many specific details for the purpose of providing a thorough understanding of the present invention. The invention may be practiced without these specific details. Furthermore, some specific details are omitted from the description in order to avoid obscuring the invention.
The term "aerosol-generating article" is used herein to describe an article comprising an aerosol-forming substrate that may be heated to generate and deliver an aerosol to a consumer.
The term "aerosol-forming substrate" means a substrate capable of releasing volatile compounds upon heating to produce an aerosol. During use, volatile compounds are released from the aerosol-forming substrate by heat transfer.
The term "aerosol-forming substrate" means or comprises an aerosol-forming substrate which upon heating is capable of releasing volatile compounds to produce an aerosol.
The higher the packing density of the aerosol-forming substrate, the higher the quality of the aerosol-forming substrate in the aerosol-generating article, when the aerosol-generating article is of a certain volume. Sufficient aerosol-forming substrate may provide sufficient smoking material, but higher or lower aerosol-forming substrate loadings may increase the difficulty of making the aerosol-generating article; a lower aerosol-forming substrate loading also affects the pumping effect, while a higher aerosol-forming substrate loading affects the re-heat capability of the aerosol-generating article and results in wastage of aerosol-forming substrate, so it is desirable to provide a reasonable aerosol-forming substrate loading density. And for the aerosol forming substrate under single density, the temperature is unfavorable for reaching or recovering to an ideal heating temperature interval during preheating and sucking, and the effective components in the aerosol forming substrate are unfavorable for being heated and evaporated well.
As one aspect of the present invention, an aerosol-generating article is disclosed comprising an aerosol-substrate comprising at least two or more aerosol-forming substrates of different densities, the aerosol-forming substrate having a packing density of from 0.3 to 0.7g/cm 3 。

aerosol formers include, but are not limited to: polyols such as glycerol, triethylene glycol; esters of polyhydric alcohols, such as glycerol mono-, di-or triacetate; and aliphatic esters of mono-, di-or polycarboxylic acids, such as dimethyl tetradecanedioate.
In certain embodiments of the present invention, the first aerosol-forming substrate is preferably prepared by a roll press process or a thick slurry process.
The rolling method is to mix tobacco powder, tobacco stem, cellulose, binder in dry state by physical method, then add a small amount of water, additives, etc. and press them into flake or thread aerosol-forming substrate by press roller, and then oven dry, roll up or cut into desired shape after demoulding.
The thick slurry method is to dry and grind crushed tobacco leaves and tobacco stems into tobacco powder, add the powder into a solution containing adhesive, combustion improver, mineral ash, humectant and reinforcing fiber to form silk slurry, coat the thick slurry on a stainless steel belt to form a film, and roll or cut the film into flake or filiform aerosol to form a substrate after drying, moisture regaining and demoulding.

The dry papermaking method uses purified air instead of water as a medium for dispersing and conveying fibers in comparison with the papermaking method by referring to the dry papermaking process.
The aerosol-forming substrate prepared by the dry papermaking method or the papermaking method has low density, high filling performance and poor aerosol releasing effect.
The second aerosol-forming substrate includes, but is not limited to, being made by a dry papermaking process or a papermaking process.
