One leaf of incense paper
On the Chinese cigarette box it says that one cigarette of incense paper is called one leaf of incense paper. The cigarettes inside the hard-shell package are purer and the tobacco is thicker. Generally, there are two layers of soft wrapping paper, the inner one is called aluminum platinum paper, and the outer one is called label paper.
The hard box has a thicker lining between the inner and outer packaging, and the outer trademark packaging paper is thicker, which increases the hardness of the packaging and is more conducive to protecting the goods.
