OIL-RESISTANT PAPER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide oil-resistant paper which can develop an oil-resistant performance only by an on-machine size press processing without using a fluorine-based oil-resistant agent. SOLUTION: This oil-resistant paper having a basis weight of 35 to 110 g / m2is characterized by impregnating paper containing natural pulp as a main component with polyvinyl alcohol in an amount of≥2 mass % based on the solid content of the pulp and then applying an on-machine size press processing to the paper. Preferably, the oil-resistant paper is produced by heating a≥5 % concentration polyvinyl alcohol at≥30°C and applying the size press processing. COPYRIGHT: (C)2005,JPO&NCIPI
