The obvious popularity of heated tobacco products in the international market is now a large percentage of market share in some markets. Heating a tobacco product to a temperature below the combustion temperature of the tobacco to heat the tobacco material to produce a smokable aerosol, often with the addition of an appropriate amount of an atomizing medium, including primarily glycerin or propylene glycol, to maintain a greater aerosol concentration. However, the above atomized medium is exposed to air and easily absorbs moisture, which causes the moisture content of the tobacco material to be too high, and influences the heating and smoke sucking mouthfeel of the tobacco material.

Particularly, after the small box package is unpacked, the tobacco material section of the cigarette is directly exposed in the air, and moisture absorption is easy to occur. When a later consumer smokes, a large amount of heat is generated in the heating process of heating the cigarette to convert absorbed moisture into water vapor, so that the energy utilization rate is reduced, and the smoking taste of the cigarette is also reduced. Research shows that the moisture absorption degree of the cigarette is directly related to the sealing degree of the cigarette, and the moisture absorption phenomenon is more serious as more water molecules enter the cigarette.
