Abstract

[Problem] To provide an aerosol generating article and a method for producing the same that can be manufactured at low cost while simultaneously improving the satisfaction of the smoking experience. [Solution] The aerosol generating article 100 may include an aerosol-forming base material section 110 that contains shredded tobacco leaves and forms an aerosol when electrically heated by an aerosol generating device, and a mouthpiece section located downstream of the aerosol-forming base material section and forming the downstream end. Since shredded tobacco leaves are less expensive than reconstituted tobacco sheets, the manufacturing cost of the aerosol generating article can be reduced. In addition, unlike reconstituted tobacco sheets, shredded tobacco leaves have fewer auxiliary materials added, so off-flavors are reduced, thereby improving the user's satisfaction with the taste.

Description

This disclosure relates to an aerosol generating article and a method for manufacturing the same. More specifically, it relates to an aerosol generating article used in conjunction with an aerosol generating device, which improves taste satisfaction while being able to be manufactured at low cost, and to a method for manufacturing the same article. In recent years, there has been increasing demand for alternatives that overcome the shortcomings of traditional cigarettes. For example, there is growing demand for devices and articles that generate aerosols through heating rather than combustion. This has led to active research on heated aerosol generating articles and devices. Many heated tobacco aerosol generating devices are manufactured using reconstituted tobacco sheets (e.g., sheet-shaped tobacco sheets) as a base. However, the high manufacturing cost of reconstituted tobacco sheets is a major factor driving up the price of aerosol generating devices. Furthermore, the manufacturing of reconstituted tobacco sheets inevitably involves the addition of auxiliary materials such as pulp and guar gum. These auxiliary materials can reduce the inherent tobacco flavor, induce off-flavors, and decrease user satisfaction with the smoking experience.
