  • The charcoal is known to have gas adsorption capability and electrical properties. Some practical applications of carbon materials for the purpose of limited electrical conduction were made in these days. In this paper, we applied the several different kinds of charcoal to the papers in three different ways to investigate if charcoal application method affects its electrical conduction capability. Wet end addition, making multiply, and coating method were tested. The area electrical resistivity of charcoal containing paper was measured. The strength properties of charcoal containing paper were compared to those of the control, which had no charcoal in it. Experimental results showed that manufacturing conditions of the charcoal itself changed its electrical and strength properties of charcoal containing paper. The electrical properties of charcoal containing paper can be used for the removal of electrostatic problem in packaging system. The strength property of the charcoal containing paper should be kept, at least, over the minimum requirement for the packaging system. By using coating method on paper or making multiply, strength loss of paper by inclusion of charcoal could be overcome.
