Ink resistance is the ability of the printed ink film to withstand harsh conditions, including light resistance, heat resistance, grease resistance, chemical resistance, etc. If printing inks and pigment blanks that require boiling sterilization packaging need to have boiling resistance.
The economical packaging and printing plant pursues low investment and high returns in printing production, that is, according to the principle of moderate packaging, and under the premise of meeting the above conditions, choose inks with lower overall cost (purchasing cost plus use cost, etc.). Although the packaging and printing plant has selected the appropriate ink, there have been many problems caused by the ink itself during the use of the ink. So, what are the higher requirements for inks for packaging and printing plants?
Packaging and printing plants' requirements for inks In order to optimize their operating costs, packaging and printing plants improve production stability and meet customer requirements, while producing high-quality products, improve production efficiency, improve production environment and meet customer requirements. The environmental protection requirements of the products are the basic requirements for inks for packaging and printing plants. Reducing operating costs, lowering costs, and obtaining maximum profits are the prerequisites for the survival and development of enterprises, and packaging and printing plants are no exception. Although ink only accounts for 15% of printing costs (paper accounts for 45%), as far as we understand, printing companies have never given up their efforts to reduce ink costs. Packaging and printing plants hope that ink suppliers will provide the best price-performance ratio to meet the requirements. Ink products. Improving ink colorability Printing plants all want ink production plants to improve the colorability of inks, and hope to use quantitative ink to print more jobs or quantitative jobs with a minimum amount of ink to reduce printing costs. However, the amount of ink is closely related to the colorability of the ink.
In the case of a certain amount of ink, the higher the colorability of the ink, the more jobs are printed and the greater the profit. On the one hand, printing companies hope that the inks used can be used directly during printing without the need to add or rarely add to the domestic plastic gravure ink market. In the current domestic plastic flexible packaging industry, Large-scale enterprises on the scale account for only about 10%, while small and medium-sized enterprises account for more than 90%.
Large-scale plastic packaging companies have advanced printing machines and fast printing speeds (high-speed printing machines); high-grade products, large batches, one-of-a-kind varieties, high-quality inks and large amounts of consumption. Generally, two or three ink manufacturers are usually used at most. Ink. However, the printing presses of many small and medium-sized plastic packaging enterprises have been updated in recent years; however, medium and low-speed printing presses still account for the majority. The equipment and conditions are poor, with more varieties, smaller batches and fewer quantities. Therefore, the use of ink is complicated, and there is no fixed ink manufacturer. The low-priced ink is generally preferred.
Ink varieties in plastic flexible packaging, food packaging, salt packaging, cosmetics and daily necessities packaging, pharmaceutical packaging, paper product packaging, clothing packaging: food packaging is mainly compound printing ink, some candy paper with surface printing ink; cooking The packaging uses high-temperature cooking ink, and the general vacuum packaging uses polyester ink; the milk product packaging should use water-resistant, acid-resistant, and temperature-resistant ink. Medicine packaging and cosmetic packaging are mainly based on polyester ink.
Some manufacturers of table salt packaging use surface printing inks, and some manufacturers use compound printing inks, but more manufacturers use polyester inks. Daily-use packaging, paper product packaging and clothing packaging mostly use surface printing ink, but surface printing white ink should be special, smooth and scratch-resistant, anti-blocking ink. With the improvement of the packaging market, more and more composite inks are used.
The price of plastic gravure ink is currently divided into high, medium and low. The ink market prices of Shanghai DlC Ink Company, Jiangmen Toyo Ink Company and Shenzhen Shenri Ink Company are higher. The ink prices of Shanxi Xiongying Ink Company and Zhejiang New Oriental Ink Company are in the middle. The price of ink for Zhejiang Yongzai Chemical Company is relatively low, but there are too many small ink manufacturers producing low-priced ink in China.
General plastic gravure ink market price: How to use alcohol-soluble gravure ink for alcohol-coated alcohol-soluble gravure printing ink, after being fully ground and dispersed by alcohol-soluble synthetic resin, solvent and organic pigment, it is a colloidal liquid with good fluidity and is volatile Drying inks have the characteristics of good printability, fast drying, bright luster and bright colors. It is suitable for printing and packaging cellophane and candy wrapping paper for food. The printing speed is 25-70m / mm.
Usage of alcohol-soluble gravure ink: It should be stored at a lower temperature, and the ink should be fully stirred before use to make it have good flow properties. The alcohol-soluble ink must meet the requirements of the machine in terms of viscosity, thinness, and drying. If the ink is too thick, it can be diluted with ethanol (which can accelerate drying) or butanol (which can slow drying), or with thinner. If the drying speed is slow due to the high speed of the printer or the winter climate, a quick-drying agent can be added to speed up the drying. The ink can be mixed with each other to adjust various colors. However, it cannot be mixed with other types of ink to avoid unusable phenomena such as resin precipitation.
