ABSTRACT:
A packing paper, superior in antibacterial activity, deodorization and electroconductivity, which is prepared by a method having the steps of making a pulp-dispersed mixture comprising 80 to 94% by weight of an aqueous pulp, 1 to 5% by weight of carbon staple 20 microns or less in diameter, and 5 to 15% by weight of acrylic staple 15 microns or less in diameter and dispersing a rosin and a mineral filler at an amount of 0.5 to 1 g and 15 to 20 g per liter of the pulp-dispersed mixture, respectively. The method further includes the step of forming the resulting mixture into a paper material. The method also includes the step of passing the paper material through several calendars maintained at a temperature of 120.degree. to 150.degree. C.
