The pet of packaging and printing: rich application of screen printing technology (on)

Nowadays, the Asian packaging market has developed rapidly, especially in China's packaging industry. With the continuous emergence and application of new materials and technologies, screen printing has a unique advantage in today's packaging and printing and is playing a huge role in providing an unprecedented variety of packaging products with unique shapes and special effects for the commodity market. The vast stage.

First, the application of screen printing on the packaging
The high flexibility of screen printing can print on the surface of various packaging products to achieve a variety of special effects. Therefore, screen printing technology is very popular in the packaging industry and is mainly applied in the following aspects:

Application on plastic packaging. Screen printing plastic film can be used for the packaging of food, clothing and Other Products, as well as the printing of plastic packaging containers.

Application on paper packaging. As the screen printing pattern has a thick ink layer and a strong three-dimensional effect, it can greatly improve the quality of packaging, and it is increasingly used in carton packaging for cigarettes, wine, cosmetics, nutritional products, and high-end footwear.

Application on metal packaging. Metal packaging mainly includes various beverage cans, food cans, and sundries. The screen printing inks used require strong adhesion, high hardness, good stretchability, and good abrasion resistance.

Application on glass packaging. Glass packaging is mainly a variety of glass bottles, used for a variety of liquid packaging, such as beverages, mineral water and a variety of beer, liquor, wine and so on.

Application on ceramic packaging. The direct method of ceramic screen printing is to print images directly onto ceramic embryos with a screen plate, and then glaze and burn to make porcelain. The indirect method is to transfer the screen-printed flower paper to the ceramic ware. Because the decal paper is printed finely, it is widely used in the ceramic packaging, such as some high-level packaging of wine.

Second, Roller screen become the preferred choice for high-grade packaging screen printing
With the development of high-quality, high-efficiency and diversified packaging net screen printing, roller screen printing has become a high-tech printing and screen printing technology with a high level of technology. Its printed products have thick ink layers, bright colors, and high density. With good force, fine lines, and seamless pattern connection, it can use large-grained printing inks to increase the three-dimensional image and the clarity of printed images. It has been widely used in many high-end carton packaging and label printing fields.

The roller screen printing system is composed of a plurality of independent monochrome printing units, suitable for various width printing, and can achieve synchronized integrated intelligent control of the production line. The key technologies in roller screen printing are screen cylinders and printing systems. The printing system uses a rubber squeegee to squeeze the ink so that it penetrates the substrate through the mesh of the drum nickel mesh. The substrate is fixed by an impression cylinder, and the screen, substrate and impression cylinder move at the same speed. A "frictionless" system. The screen printing machine structure is stable and durable, the screen can be used repeatedly, overprinting is accurate, and the speed is fast. It has a simple and convenient job conversion control system, the downtime of the replacement work is very short, and the equipment can achieve higher output, suitable for Printing products with a large number or often repeated printing is the preferred model for packaging screen printing, and it is also a type of machine widely used in the domestic packaging printing industry.
