Screen printing is a more traditional printing process. Although the proportion of screen printing in the entire printing market is very small, but since the 1980s, its development speed has been in front of printing methods such as flat, convex and concave. The annual growth rate of advanced countries in the world has reached 8% to 10%, and there are also more than 260 screen printing equipment and equipment manufacturers in China, employing about 150,000 people, producing about 50 kinds of screen printing products, and the annual consumption of about 50,000 in the country. In recent years, with the continuous improvement of the people’s living standards, everyone’s demand for packaging is no longer limited to the protection of goods and convenience of transportation, and higher requirements have been placed on packaging, decoration, and design.
The range of screen printing printing materials is very wide, and more materials are used in packaging. There are applications such as plastic, paper, metal, glass, ceramics, and various composite packaging materials printed on plastic packaging. The following describes the application of two inks on printing and packaging materials:
First, the application of plastic packaging
Materials commonly used in plastic packaging are: polyethylene (mainly high pressure and low pressure polyethylene), polypropylene, polyvinyl chloride, polyvinylidene chloride, and polyester. Most of the screen printing inks used in plastic packaging belong to the volatile drying type, requiring good printability, fluidity, resistance to netting and adhesion.
Second, the application of paper packaging
As the screen printing pattern has a thick ink layer and a strong three-dimensional effect, the grade of the packaging can be greatly improved. General paper packaging commonly used materials are mainly used in high-grade paper and cardboard, such as glass cardboard, gold cardboard, silver cardboard and so on. It is characterized by small fiber pores and a close texture. This series of inks are required to have light resistance, heat resistance, solvent resistance and abrasion resistance in printing.
