In the early paper packaging industry, coated paper was usually only used in offset printing or preprint. Because the characteristics of coated paper itself are most suitable for offset printing.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

       The traditional corrugated paper printing and packaging is also limited to rough Kraft linerboard and vermicelli white kraft linerboard.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

         The products are only some prints with simple printing content. Because the configuration of the traditional corrugated ink printer is limited and the traditional water-based ink is used, it is difficult to overcome some common technical problems when printing coated paper. Because there is a coating layer on the surface of the coated paper, which fills the fiber connection pores on the surface of the paperboard. 

      When the ink is printed on the coating surface, the wet ink is difficult to penetrate into the paperboard through the sealed coating, so the ink on the printing surface is difficult to be dried by penetration, but can only be dried by natural volatilization. Therefore, ink printing on coated paper is mainly manifested in the difficulty of ink drying. Advantages Of Flexographic Printing For Coated White Kraft Linerboard

      The drying speed of ink is slow. In the printing process, it is easy to lead to a series of problems, such as blotting, smearing, difficult overprint, decolorization, rewetting, slow printing speed and so on.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

       As coated kraft linerboard has high gloss printing surface and bright and full coloring effect, as well as clear imprinting on the paper surface, and the overall printing effect is bright, which is beyond the reach of ordinary Kraft linerboard, it will be more attractive to use coated kraft linerboard for printing in outer packaging cartons.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

       Therefore, the end users of many brand packaging boxes are also willing to use coated paper as the outer packaging box. At present, many carton users for export or domestic sales in China have successively changed from using white cow card paper to coating white cow card as outer packing box.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

       In addition, the packaging market is also developing in another direction of reducing product costs. Some users with large carton size, simple printing layout design and low accuracy requirements also gradually convert the original offset outer packaging box to corrugated paper direct flexographic printing.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

       Due to the high cost of offset printing, many post-processing processes and long time-consuming, offset printing is limited by the range of printing press and can not print wide products.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

        In addition, the ink binder and solvent used by offset press are toxic. Long term contact with people will be harmful to human health and is not suitable for the requirements of environmental protection. Advantages Of Flexographic Printing For Coated White Kraft Linerboard

      Flexographic printing mainly uses environmental friendly ink. Due to the advantages of flexographic printing and the continuous improvement of flexographic printing technology, and the printing level is close to the offset effect, the share of flexographic printing products in the packaging market is increasing year by year.Advantages Of Flexographic Printing For Coated White Kraft Linerboard

         The development trend of packaging printing will mainly adopt flexographic direct printing with environmental protection, low cost and saving processing time. Advantages Of Flexographic Printing For Coated White Kraft Linerboard

        Due to the awareness of environmental protection, in the economically developed countries in Europe and America, most of the outer packaging cartons are flexographic printing, while the products exported to Europe and America are more popular and more acceptable
