Cooling filter rod, application thereof and cigarette

Abstract

A cooling filter rod, an application, and a cigarette are provided. The cooling filter rod is mainly formed by cooling particles. The cooling particle includes a particle body and a shell coated on the particle body. The shell or the particle body contains a phase change material. The phase change material is coated on the surface of the particle material to form cooling particles, and the cooling particles are integrally formed into a cooling filter rod, which can be directly used for cigarette production after being compounded with conventional filter rods. The cooling effect can be controlled according to the amount of the phase change material and the cooling filter rod. Such a filter rod can realize industrial production and has low cost and good cooling effect.
