    摘要: A method of preparing biodegradable, water-resistant, moldable paper board or molded paper utensil which includes the steps of: (a) preparing a pulp aqueous slurry at a consistency of about 4%; (b) adding surfactant selected from the group consisting of rosin soap, sodium oleate, sodium stearate, and sodium palmitate to the pulp aqueous slurry; (c) adding between 25-75% weight of a biodegradable and water-resistant agent selected from the group consisting of calcium stearate, cellulose stearate, calcium palmitate and cellulose palmitate to the pulp aqueous slurry to form a slurry mixture; (d) refining the slurry mixture at a consistency of about 4% to a desired drainage; (e) diluting the refined slurry mixture and adding thereto an aggregating agent as alum to form a furnish; (f) forming the furnish to obtain a dry moldable soft paper board; (g) preheating the moldable paper board obtained in step (f) at a temperature from 110.degree. to 170.degree. C.; and (h) hot-pressing the preheated moldable paper board obtained in step (g) in a mold at a temperature from 115.degree. to 170.degree. C. for 2 to 40 seconds to obtain a molded paper utensil.

    摘要: 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.
