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. Insufficient adhesion of the ink on the calcium plastic material makes the ink 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. 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 ink on calcium plastic materials, Lisheng Chemical Materials Research Institute of Wuhan University has successfully developed a calcium plastic box ink using new technologies. This ink is printed using three primary colors of ink, creating a domestic calcium plastic ink printing. New chapter. It is made from a variety of composite resins, organic pigments and new additives. The appearance of the printed matter is high in gloss, good in brightness, fast in drying, good in fastness of attachment, clear in design and full in level. With good chemical resistance, good resistance to temperature changes, abrasion resistance and other advantages. The product can be widely applied to the surface printing of various foods, pesticides, chemical reagents, cold collections, parcels and other packaging, and can be multi-color, multi-color screen printing. Designed with an annual output of 200 tons of water-based ink, equipment investment of 60,000 yuan, plant 150m2, power 20KW, domestic raw materials easy to purchase. The raw material cost is 16,000 yuan/ton, the reference ex-factory price is 26,000 yuan/ton, the annual production value is 5.2 million yuan, and the annual profit and tax is 2 million.
