PP 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, no environmental pollution, and gas permeability. Good, widely used in the printing of high-end art, maps, albums, high-end books and so on.
　　 The synthetic polymer material (such as polyethylene, polypropylene, etc.) is made into a semi-finished paper sheet by pulling film (pressing film or blown film), and then using a chemical or physical method to make it paper, such as sanding can increase Transparency, the treatment of the surface with chemicals can achieve sputum performance. Another type of synthetic paper product can be made from synthetic pulp, which is processed after beating. Synthetic paper has extremely high tensile strength, extremely high tear strength, good insulation properties, optical properties and excellent wet strength. Used as insulation materials, sea drawings, military map paper, etc.
　　 Also known as chemical film paper, polymer paper, plastic paper, etc.
　　 The main raw materials are organic resins such as polyethylene, polypropylene, and polystyrene. In the method, the resin is first melted, extruded, and formed into a film, and stretched in different axial directions to form a film; then, the film is subjected to a "paper-like" treatment to make it opaque and whiteness is improved. Thus, synthetic paper was produced. The paper has high tensile strength and is not afraid of water, insects, elasticity, heat insulation, dimensional stability, smooth surface, and is suitable for books and printing. It is mainly used for making fishery paper, nautical charts, wearing hole cards, water-resistant newspapers, record bags, merchandise labels, outdoor advertisements, business cards, etc. The disadvantage is that the folding resistance is poor, and there are creases that are not easy to disappear after folding. It is difficult to recycle waste synthetic paper.
　　 The types of synthetic papers are classified into PP synthetic paper, HDPE synthetic paper, PS synthetic paper, PVC synthetic paper, PET synthetic paper, ABS synthetic paper, etc. according to different raw materials; according to different fillers, CaCO3 (calciumcarbonate) is filled. Type, clay (main component SiO2, Al2O3) type, SiO2 (silica) type, mica (talc) type, TiO2 (titanium dioxide) type and composite (two or more types), etc.; according to different production methods, Divided into calendering method (such as soft PVC), casting method (such as CPP), blown film method (such as HDPE), biaxial stretching method (such as BOPP, BOPET), etc.; according to different structures, divided into single-layer synthetic paper , three-layer synthetic paper, five-layer synthetic paper, and the like.
