Three primary color calcium plastic box ink

Due to its excellent water resistance, chemical resistance, and temperature resistance, calcium plastic boxes are widely used in special packaging fields such as food, pesticides, chemicals, and refrigeration. The traditional calcium plastic box ink has the following problems: 1. The adhesion of the ink on the calcium plastic material is not enough, so that the ink is easily detached from the calcium plastic box. 2. In general, only some line drawings and large-area color blocks are printed on the calcium plastic material, that is to say, basically, spot color printing is used, and there is rarely four-color overprint for screen printing. 3, ink in the calcium plastic material gloss is not enough. 4, drying speed is slow. 5, unstable performance. It is precisely because of the above problems that the color and the level of the graphic and text are affected. It is rare to see a beautiful graphic on the calcium plastic material, which affects the appearance of the calcium plastic box and further affects the application of the calcium plastic material.

In order to solve the problem of printing adaptability of inks on calcium plastic materials, the printing and packaging department of Wuhan University has successfully developed a calcium plastic box ink using the new technology. The ink is printed using three primary colors of ink, creating a new chapter in the printing of domestic calcium plastic inks. . It is made from a variety of composite resins, organic pigments and new additives. The appearance of the printed matter is high glossiness, good brightness, fast drying, good fastness of attachment, clear pattern, full height, good chemical resistance, good resistance to temperature change, and abrasion resistance. The products can be widely applied to the surface printing of calcium plastic boxes of packaging products such as various foods, pesticides, chemical reagents, cold collections, postal parcels, etc., and can be screen-printed in multi-color and chromatic colors.
