Paper is an essential material in our daily lives. Paper is made of wood which is renewable and is a symbol of recycle-based resources because it has established a recycling system. Therefore, expanding the possibilities of paper is very important for a sustainable society. Our products contribute to the expansion of the applicable area of paper by adding various functions such as strength and water-resistant etc. In recent years, we have been developing functional coating agents for paper. We aim to use paper materials to replace the plastic films used in packaging materials, and we are pursuing further possibilities for paper.
