Mitsubishi Paper Mills Limited

Mitsubishi Paper Mills is a paper manufacturer affiliated with the Mitsubishi and Oji groups. Its defining feature is the shift toward a combination of coated paper, including premium glossy paper, and functional materials such as battery separators, nonwovens, and glass fiber paper. Its core business remains coated and communication papers, but it is actively expanding into functional materials—especially lithium-ion battery separators, nonwovens, and glass fiber paper. It is a paper and functional-materials company extending from paper into batteries, filtration, and electronic materials.
