The amount of menthol contained in the non-combustion heated smoking article is larger than the amount of menthol contained in the evaluation non-combustion heated smoking article produced in Example 1.
  • Example 1 in which the wrapper was provided with the polymer layer containing menthol, the menthol supply efficiency was substantially uniform in the first to fourth puffs. It is speculated that menthol was gradually released from the polymer layer.
  • Comparative Example 1 in which the tobacco filler contained menthol and the wrapper was not provided with the menthol-containing polymer layer, the menthol supply efficiency decreased linearly from the first puff to the fourth puff. Most of the menthol contained in the tobacco filling was vaporized in the first half of the suction.
  • Example 1 in the total of 4 puffs, the menthol supply efficiency in Example 1 was higher than that in Comparative Example 1. This is presumably because in Example 1, the menthol was contained in the polymer layer of the wrapper, and the polymer layer of the wrapper was located near the heater of the heating device during heating. In addition, since the initial amount of menthol contained in the non-combustion heating smoking article is different between Example 1 and Comparative Example 1, the comparison was performed based on the menthol supply efficiency in FIG. 6 and Table 1.
  • Example 1 no stain was confirmed on the surface of the wrapper, whereas in Comparative Example 1, a stain was confirmed. It is speculated that in Example 1, the presence of the polymer layer could suppress the exudation of the aerosol-forming base material, the tobacco component and the volatile fragrance component contained in the tobacco filler.
