Wrapper comprising metal particles

Abstract

A wrapper according to an aspect includes a pulp layer and metal particles uniformly distributed inside the pulp layer, wherein the metal particles contain a metal flake paste.

1 . A wrapper comprising:
 a pulp layer; and   metal particles uniformly distributed inside the pulp layer,   wherein the metal particles contain a metal flake paste.   
     
     
         2 . The wrapper of  claim 1 , wherein the metal flake paste is made of aluminum, steel, iron, copper or a metal alloy. 
     
     
         3 . The wrapper of  claim 1 , wherein the metal flake paste is made by a method including:
 a first process of flaking raw material aluminum powder in an organic solvent containing aromatic hydrocarbons as a main component to obtain aluminum flakes; and   a second process of treating the aluminum flakes obtained in the first process with an organic compound having a polar group and forming a paste.   
     
     
         4 . The wrapper of  claim 3 , wherein the organic compound having the polar group is at least one selected from the group consisting of fatty acids, aliphatic amines, fatty acid amides, aliphatic alcohols, and esters composed of fatty acids and aliphatic alcohols. 
     
     
         5 . A cigarette comprising:
 a tobacco rod containing an aerosol generating material;   at least one filter segment; and   a wrapper that wraps at least one of the tobacco rod and the at least one filter segment,   ein the wrapper comprises:   a pulp layer; and   at least one metal particle distributed inside the pulp layer, and   wherein the metal particle contains a metal flake paste.   
     
     
         6 . The cigarette of  claim 5 , wherein the metal flake paste is made of aluminum, steel, iron, copper, or a metal alloy. 
     
     
         7 . The cigarette of  claim 5 , wherein an aerosol is generated from the tobacco rod by an electric-heating-type heater inserted into the cigarette. 
     
     
         8 . A method of manufacturing a metal flake paste, the method comprising:
 a first process of flaking raw material aluminum powder in an organic solvent containing aromatic hydrocarbons as a main component to obtain aluminum flakes; and   a second process of treating the aluminum flakes obtained in the first process with an organic compound having a polar group and forming a paste.   
     
     
         9 . The method of  claim 8 , wherein the organic compound having the polar group is at least one selected from the group consisting of fatty acids, aliphatic amines, fatty acid amides, aliphatic alcohols, and esters composed of fatty acids and aliphatic alcohols.
