Application of UV Flexographic Ink in Corrugated Cardboard

Date: Feb 26 2025 From: Star Color

With consumers' continuous pursuit of product quality and the enhancement of environmental awareness, packaging printing not only needs to meet the aesthetic and clear visual requirements but also comply with strict environmental protection standards. In such a situation, UV flexographic ink has begun to stand out in corrugated cardboard printing and its application range is becoming increasingly wider. The UV flexographic printing technology skillfully integrates the high flexibility of flexographic printing and the high efficiency of UV curable inks, opening a door to excellent quality and sustainable development for the corrugated cardboard printing industry.

Working Principle of UV Flexographic Ink

UV flexographic ink is a special ink that is cured by ultraviolet (UV) light. During the printing process, the flexographic printing press, with its unique working mechanism, precisely transfers the ink onto the surface of the corrugated cardboard. Subsequently, the ultraviolet light emitted by the UV lamp irradiates the ink, instantly triggering a photochemical reaction. In this process, the ink molecules rapidly undergo a polymerization reaction, transforming from a liquid state to a solid state within just a few seconds, achieving rapid curing. Compared with traditional inks that mainly rely on solvent evaporation or thermal drying for curing, UV flexographic ink does not require a long waiting time, greatly shortening the production cycle, significantly improving production efficiency, and saving a large amount of time and cost for enterprises.

Application Scenarios of UV Flexographic Ink in Corrugated Cardboard Printing

Food Packaging
- Advantages: UV flexographic ink complies with the FDA food contact standard, and it is safe and non-toxic. This characteristic makes it an ideal choice for the food packaging field. During the food packaging process, corrugated cardboard boxes printed with UV flexographic ink can ensure the safety and hygiene of food, allowing consumers to consume it with confidence.
- Case: An internationally renowned food brand used UV flexographic ink to print corrugated cardboard boxes for its products. By using this ink, the brand's production efficiency was significantly improved, increasing by 30% compared to before. At the same time, due to the environmental protection characteristics of UV flexographic ink, the brand better met the market's requirements for environmentally friendly packaging, enhancing its brand image and market competitiveness.
Electronics Packaging
- Advantages: UV flexographic ink has the characteristics of scratch resistance and chemical resistance, which can effectively protect electronic products from damage during transportation. During the transportation of electronic products, they are often subjected to various frictions, collisions, and the erosion of chemical substances. The application of UV flexographic ink can provide reliable protection for electronic products.
- Case: An electronics manufacturer used UV flexographic ink for the printing of anti-static packaging. Through practical application, the manufacturer found that the product damage rate was significantly reduced. This not only reduced the enterprise's losses but also improved product quality and customer satisfaction. Meanwhile, the rapid curing characteristic of UV flexographic ink also increased production efficiency, bringing tangible economic benefits to the enterprise.
Retail Display Packaging
- Advantages: UV flexographic ink can endow corrugated cardboard with high gloss and vivid colors, making retail display packaging more attractive to consumers. In the highly competitive retail market, an exquisite display packaging can stand out among numerous products, attracting consumers' attention and thus promoting product sales.
- Case: A retail brand used UV flexographic ink for the printing of its display boxes. By using this ink, the appearance of the display boxes became more beautiful and the colors became more vivid, greatly enhancing the shelf appeal of the products. After consumers saw these exquisite display boxes, their purchasing desire increased significantly, and the brand's product sales also increased remarkably.

Challenges and Solutions

High Initial Investment: Although UV flexographic ink has many advantages, when enterprises introduce this technology, they often face high initial investment, including equipment upgrades and renovations, and ink procurement. However, in the long run, through the energy-saving characteristics of UV flexographic ink and the advantages of reducing waste, enterprises can quickly achieve a return on investment. For example, the low energy consumption of UV LED lamps can reduce the enterprise's energy costs, and the reduction of paper waste due to instant curing can also save a large amount of costs for the enterprise.

Ink Compatibility: When using UV flexographic ink, the compatibility between the ink and the equipment is a key issue. Different equipment and inks may be incompatible, resulting in a decline in printing quality or equipment failures. To solve this problem, enterprises should choose reliable UV ink suppliers, such as Huizhou Zhongzhixing Color Technology Co., Ltd. The company has a professional technical team and rich experience, which can ensure the compatibility between the ink and the equipment and provide high-quality products and services for enterprises.
Operator Training: There are certain differences in operation between UV flexographic printing technology and traditional printing technology. Therefore, comprehensive technical training is required for operators. Through training, operators can master the operation key points and precautions of UV flexographic printing technology proficiently, improving printing quality and production efficiency. At the same time, enterprises should also establish a complete training system, regularly train and assess operators to ensure the continuous improvement of their technical levels.
