Food-grade offset printing ink is a printing ink that is specially used in the field of direct or indirect contact with food, such as food packaging. It is made of raw materials that meet food safety standards, and the content of harmful substances, such as heavy metals, organic solvent residues, etc., is strictly controlled in the production process to ensure that it will not cause contamination to food. Compared with ordinary offset printing inks, food-grade offset printing inks have higher safety and environmental protection, and also have good printability, which can achieve clear and accurate pattern and text printing in the offset printing process, rich color performance and good stability, moderate drying speed, and the ink film formed has a certain water resistance, friction resistance, etc., which can meet the needs of food packaging in terms of appearance decoration and information transmission under the premise of ensuring food safety.
First, the working principle of food-grade offset printing ink
The work of food-grade offset inks is based on the special properties of the printing plate. The printing plate graphic part is lipophilic, and the blank part is hydrophilic. When printing, water is supplied to the printing plate first, so that the blank part forms a water film, and then the ink is supplied, and the ink will only adhere to the graphic part. Then, the ink on the graphic part of the printing plate is transferred to the substrate such as food packaging through a blanket cylinder. Finally, the ink is dried by solvent volatilization, oxidative polymerization or ultraviolet curing, so that pigments and other components are firmly attached to the surface of the substrate to complete the printing process. In addition, the ink raw materials used in the entire process meet food safety standards to ensure safety when in contact with food.

(2) Quality control of its own factory
The self-owned production plant helps to establish a strict and perfect quality control system. From the entry of raw materials, the production process to the delivery of finished products, all links are strictly inspected and tested to ensure stable and reliable product quality.
(3) Supply chain under the advantages of ports
Proximity to ports brings supply chain advantages, reducing logistics costs and speeding up transportation. It can easily obtain high-quality raw materials from all over the world, optimize suppliers, optimize the supply chain, ensure stable supply, reduce procurement costs, and improve product cost performance and market competitiveness.
(4) Improve the team's rapid response
Perfect corporate team building promotes smooth internal communication, efficient collaboration. In the face of customer problems or special needs, we can respond quickly, organize discussions and formulate plans, quickly meet needs, improve customer satisfaction and loyalty, and establish a good corporate image.
(5) Environmental protection and sustainable development
In the context of increasing environmental awareness, with the help of the research and development capabilities of the professional team, we will develop more environmentally friendly food-grade offset printing inks, such as using renewable resources and reducing VOC emissions. Comply with market demand, enhance the social image and brand value of enterprises, and enhance market competitiveness.
(6) Diversified product system
Combined with our own factories, the professional team can develop and produce a variety of food-grade offset printing inks according to customer and market demand, covering special inks for different packaging materials and special process inks, providing rich choices and one-stop solutions.
(7) Cost control and price advantage
In all aspects of raw material procurement, production and processing, logistics and transportation, we have strong cost control capabilities. The self-owned factory optimizes the process, improves efficiency and reduces costs, the port advantage reduces logistics costs, the professional team plans reasonably to avoid waste, and the product price competitiveness is strong, so as to provide customers with cost-effective products.
Third, advantages compared with other ink products
(1) Safety and health are more assured
Ordinary inks usually contain heavy metals, harmful solvents and other substances, when in contact with food, these harmful substances can easily migrate into food, posing a serious threat to human health. The food-grade offset printing ink strictly follows the food safety standards, strictly screens and controls the raw materials, and almost does not contain harmful substances, which can effectively eliminate the problem of food contamination, effectively protect the health of consumers, and let customers use it with peace of mind.
(2) Better environmental performance
Traditional inks release a large number of volatile organic compounds (VOCs) during production and use, causing serious pollution to the environment. The use of environmentally friendly raw materials and advanced production technology for food-grade offset printing inks greatly reduces VOCs emissions and reduces the impact on the atmospheric environment, which is in line with the current development trend of green environmental protection, helps customers enhance their own environmental protection image, and jointly contributes to the protection of the environment.
(3) The printing performance is more stable
Food-grade offset printing inks are specially designed for the offset printing process, and their ink transfer performance is good, which can achieve accurate graphic printing, so that the dots are clear and the colors are bright. Moreover, under different printing conditions (such as temperature and humidity changes), its performance is still stable, which can ensure the consistency of printing quality, reduce the defective rate, improve production efficiency, and save time and cost for customers.
(4) Strong resistance and longer lasting
In the process of storage and circulation, food will inevitably come into contact with water, grease, acid and alkali and other substances, and ordinary inks are prone to fade, dissolve, fall off and other problems in this case. The food-grade offset printing ink has excellent water resistance, oil resistance and chemical corrosion resistance, which can maintain the integrity of the pattern and the stability of the color in a complex environment, prolong the service life of food packaging, improve the display effect of products on the shelf, and better attract the attention of consumers.
(5) The material adapts to a wider range
There are many types of food packaging materials, including paper, plastic, metal, glass, etc. Food-grade offset printing ink is specially formulated and designed, which has good adhesion and compatibility with a variety of materials, and can achieve high-quality printing on the surface of different materials to meet the diverse packaging needs of customers. However, ordinary inks may only be suitable for specific materials, and the application range is relatively narrow, which cannot meet the diverse needs of the market.
(6) Regulatory compliance is more compliant
The food industry has strict regulations and standards for the use of packaging inks. The use of food-grade offset printing ink can ensure that the product meets the requirements of relevant laws and regulations, avoid the risk of product recall, fines and other risks caused by ink problems, and maintain the reputation and interests of the enterprise. The use of non-compliant inks may cause customers to fall into legal disputes, suffer economic losses, and affect the normal operation of enterprises.
Third, the wide application of food-grade offset printing ink
(1) Food packaging field
1. Paper packaging: often used in biscuits, candies and other food cartons, paper bags, printed with exquisite pattern text, enhance the attractiveness of products.
