  • General ‘paper’ is made up of intertwined pulp fibers and has many spaces, making it easy for oxygen and water vapor to pass through. That is, there is no barrier property that can prevent moisture, oxygen, and other substances introduced from the outside from penetrating into the interior. Therefore, most packaging paper is treated with a barrier coating, and the most widely used method is laminating polyethylene (PE), and latex coating is also being considered. These materials are excellent in terms of providing moisture resistance, but because they are petrochemical carbon compounds, they have the disadvantage of being difficult to biodegrade and not being environmentally friendly. Therefore, there is an urgent need to discover new natural materials that can replace petrochemical raw materials and expand their use.
