Date: Aug 20 2024 From: Star Color
With the continuous improvement of food safety awareness and the increasingly strict requirements of consumers for packaging quality, the selection of food grade materials and optimization of printing processes have become important issues in the food packaging industry. UV offset printing ink, as an efficient, environmentally friendly, and brightly colored printing material, is gradually demonstrating its unique advantages in the printing field of food grade materials.
1. Basic characteristics of UV offset printing inkUV offset printing ink is an ink that can quickly cure under ultraviolet light irradiation. It is mainly composed of prepolymers, active monomers, photoinitiators, and pigments, and has the characteristics of short curing time, stable printing quality, high production efficiency, and environmental friendliness without pollution. The characteristics of UV offset printing ink make it have good application prospects in the printing of food grade materials.
Characteristics of UV offset printing ink:
1.1 Rapid curing
UV offset printing ink can quickly cure under ultraviolet irradiation, which significantly improves the speed and efficiency of printing production. Compared to traditional ink, the curing time of UV ink is greatly shortened, greatly improving printing efficiency.
1.2 High glossiness
The cured UV offset ink surface has excellent glossiness and visual effects, making printed materials more vivid and lively. This high glossiness not only enhances the overall texture of printed materials, but also strengthens the product's market competitiveness.
1.3 Strong wear resistance
After curing, UV offset printing ink forms a hard film with excellent wear resistance. This wear resistance enables printed materials to maintain good appearance quality during long-term use and transportation, extending the product's service life.
1.4 Color stability
UV offset printing ink has excellent color stability and is not easily affected by light, oxidation, or chemical reactions. This feature ensures that printed materials can maintain vibrant colors during long-term storage and display without fading or discoloration.
1.5 Environmentally friendly and pollution-free
UV offset printing ink does not require the use of organic solvents during the curing process, so it does not produce harmful substances such as volatile organic compounds (VOCs). This characteristic makes UV ink an environmentally friendly printing material that meets the current global requirements for environmental protection and sustainable development.
1.6 Widely applicable
UV offset printing ink is suitable for various substrates, including paper, plastic, metal, glass, etc. This wide applicability makes UV ink widely used in various fields such as food packaging, pharmaceutical packaging, cosmetics packaging, electronic product packaging, etc.
1.7 Security
The chemical substances in UV offset printing ink are strictly screened and tested to ensure that they do not contain harmful substances and do not pose a threat to the environment and human health.
2 The application advantages of UV offset printing ink on food grade materialsFood safety: The raw materials of UV offset printing ink are strictly screened to ensure that they do not contain harmful substances such as heavy metals, organic solvents, etc. During the curing process, these substances will not migrate into the food, ensuring the safety of the food. In addition, UV ink also has good corrosion resistance and can resist the acidity and alkalinity of food, ensuring that it will not contaminate food during long-term storage and use.
Excellent printing effect: UV offset printing ink has bright colors and high saturation, which can present delicate patterns and text, enhancing the visual effect of food packaging. At the same time, UV ink also has excellent wear resistance, light resistance, and water resistance, allowing printed materials to maintain good appearance quality during long-term use and transportation.
Environmentally friendly and pollution-free: UV offset printing ink does not require the use of organic solvents during the curing process, so it does not produce harmful substances such as volatile organic compounds (VOCs), reducing environmental pollution. This feature is in line with the current global requirements for environmental protection and sustainable development, and also meets consumers' demand for green packaging.
High production efficiency: UV offset printing ink has a fast curing speed, which can complete the drying and curing process of printed materials in a short period of time, thereby improving production efficiency. This is particularly important for the food packaging industry, as fast production cycles can shorten product launch time and enhance market competitiveness.
3. Application of UV offset printing ink on food grade materialsIn the field of food packaging, UV offset printing ink has been widely used in the printing of various food grade materials. For example, in the printing of food packaging materials such as paper, plastic film, aluminum foil, and metal, UV offset printing ink can not only present exquisite patterns and text, but also ensure the safety of food.
Zhongzhixing UV offset printing ink has extremely high curing efficiency, which can quickly complete the curing process under ultraviolet irradiation, greatly improve production efficiency, significantly shorten production cycles, and enable enterprises to respond to market demand faster. The cured surface has extremely high glossiness, bright and full colors, which can perfectly present the details of printed materials and enhance the overall visual effect and texture of the product.
In addition, Zhongzhixing UV offset printing ink has excellent wear resistance and weather resistance, which can maintain the clarity and aesthetics of printed products in various harsh environments. At the same time, the ink produces almost no volatile organic compounds (VOCs) during the curing process, which meets environmental requirements and provides strong support for enterprises to practice green production.
More importantly, the safety of Zhongzhixing UV offset printing ink is strictly guaranteed, and its raw materials are carefully screened to ensure that they do not contain harmful substances and will not pose any threat to the environment and human health. This characteristic has made the ink widely used in fields such as food packaging and pharmaceutical packaging that require high safety.
