[0002] BOPP cigarette film, also known as biaxially oriented polypropylene cigarette film, or cigarette film for short, is formed by co-extrusion and stretching of a variety of polypropylene functional materials.

It has high transparency and glossiness. The material is non-toxic, has a stable molecular structure, and has a certain barrier function to odor and moisture. Therefore, it is an ideal material for cigarette packaging. In the production process, the rolled BOPP cigarette film needs to be cut and re-rolled.
