Flexo Printing Provides Technical Support for Upgrading Dairy Packaging

With the strengthening of people’s awareness of environmental protection, dairy packaging, which is one of the daily consumer products of people, gradually moves toward green packaging. Most manufacturers gradually move towards flexo printing. This is mainly due to the unique advantages of the flexo printing process:

Use water-based inks. Since water-based inks do not contain volatile organic solvents, certain toxic and harmful substances in solvent-based inks can be eliminated, which reduces the contamination of the inner packaging products. In addition, in the production process, the water-based ink is not easy to fall off after curing, avoiding the appearance of the ink layer falling off when the liquid product is packaged and used. Therefore, the use of water-based inks meets the environmental requirements for food packaging with high hygienic requirements such as dairy products and fruit juice drinks, which, to some extent, promotes the application of flexographic printing methods in this field. Anilox roller is used to transfer ink. Flexo printing is the use of anilox roller to achieve ink transfer, not only shortens the ink transfer path, but also can ensure accurate ink transfer amount, ensure uniform thickness of the ink layer in the production process, and then achieve dairy packaging and decorating design Beautiful.

Wired processing. Flexo printing equipment is relatively easy to realize post-print cutting, glazing, gluing, and other in-line processing, which not only accelerates work efficiency to a great extent, but also can improve the accuracy of printing processing to some extent. In this respect, the flexo printing method is very suitable for the processing of dairy packaging.

Dairy packaging flexible printing has achieved certain applications and attention in the European and American markets, but it is still in its infancy in China. However, some processors have purchased flexographic printing equipment domestically or abroad to engage in dairy packaging and processing, and in this area Get a certain development.

Flexible printing technology has been rapidly developed abroad, especially in the printing of packaging materials, flexo printing has exceeded the trend of printing and gravure printing in the printing market share of the packaging industry. Compared with gravure printing, it reduces the cost of plate making and shortens the plate making cycle. Compared with offset printing, the types of substrates are greatly increased. In particular, non-toxic water-based inks used in flexo printing are far behind gravure and offset printing. Therefore, it is widely used for the packaging of food and medicine.

The flexographic printing plate has the characteristics of three printing processes: flat printing, four printing, and embossing. The flexibility of the printing plate is similar to the contact between the printing blanket and the printing material in printing, and the ink transmission performance is good; the flexible printing plate is a relief printing plate with Embossing features; waterless, direct printing; ink layer after only one separation; flexographic printing presses are used round-round multi-color rotary press printing. Flexographic printing has become a new type of printing process that has grown rapidly and avoids the shortcomings of the three. High-precision color prints of 150 lines, 6 colors, -8 colors, or more are suitable. The ink layer thickness of printed matter makes the product rich in layers and vivid colors, which is especially suitable for packaging and printing requirements. In particular, the unit type flexo direct printing (post-printing) is a low-cost, high-quality carton printing program, which has the following characteristics: Flexo printing plates are light and printing pressure is light; flexo printing can be illustrated, graphic and clear; printing plates Soft, flexible, good ink transfer performance, wide application of printing materials, low scrap rate, low cost; no matter the size of the carton, the thickness is one piece; the flatness of the flexographic plate is high, the time of the plate is short, the speed is fast, and the low cost is fast Change orders; simple process flow operation method; flexographic printing press structure is simple, using short ink ink system, low investment, large output, high returns; is environmentally friendly and energy-saving printing methods, to provide technical support for the carton upgrade.

Although the start of flexographic printing was relatively late, its development was unusually rapid. According to statistics, at present, the market share of flexographic printing in the United States accounts for 70% in the field of flexible packaging, 85% in label printing, and 90% in corrugated boxes. This is the advantage of flexographic printing. Flexo ink is the only non-toxic ink approved by the American Food and Drug Association in all printing inks. Therefore, it is widely used in the packaging and printing of foods and dairy products. Such as: the printing of corrugated boxes, the printing of plastic flexible packaging, the printing of dairy composite packaging materials, Tetra Pak, the printing of Tetra Pak and the printing of labels, etc.
