Shell for heat-not-burn tobacco

Abstract

The present invention provides a casing for a heat-not-burn ceramic film cigarette, the casing comprising a main body cigarette tube, sealing paper located at one end of the cigarette tube, and a filter tip located at the other end of the cigarette tube. A ceramic film is arranged, in the cigarette tube, on a contact layer that comes into contact with tobacco. A ceramic film is provided on the contact face of the sealing paper that comes into contact with the tobacco. According to the casing for a heat-not-burn cigarette provided in the present invention, the ceramic film of the casing is directly applied to a packaging layer which comes in direct contact with the tobacco, such that the component stability of a heat-not-burn cigarette can be greatly increased, and the moisture retention property of tobacco substances is significantly improved.

What is claimed is:
