Synthetic paper: Synthetic paper is made by using chemical raw materials such as olefins and adding some additives. It has soft texture, strong tensile strength, high water resistance, light and cold resistance, corrosion resistance against chemical substances and no environmental pollution. It has good air permeability and is widely used in the printing of high-end artworks, maps, catalogues, high-end books and magazines.
