Manufacturing Method

The thickness of the product is determined by the number of sets of Fibre base paper. In addition, continuous operation is performed by adding Fibre base paper.
The Fibre base paper is impregnated with zinc chloride solution and then laminated to form a raw sheet.
Zinc chloride is recovered and reused in the water washing process.
Raw sheets are dried to the specified moisture by a dryer, and finished into rolls or boards after calendering.
