Application of edible ink in food packaging

with the improvement of living standards, people put forward higher requirements for food packaging. As a printing material, ink must abide by the principle of no transfer when it is used in food packaging. Conventional ink shall not be used for food packaging. The printing manufacturer must ensure that all solvents in the ink evaporate after printing, and the ink shall be cured thoroughly and meet the corresponding standards of the application industry

in the current food plastic packaging printing, benzene soluble chlorinated polypropylene ink is the most widely used. The manufacturing and application technology of this kind of ink has been mature. It is mainly used in the inner printing of BOPP (biaxially oriented polypropylene) materials, and gravure printing is adopted

food packaging ink quality certification is an internationally accepted evaluation method of products, processes and services. It is gradually formed as an external quality assurance means with the development of modern industry. Through legislation or promulgation of compulsory certification system for some products involving human health, environmental protection and safety, the legitimate rights and interests of the state and the general public are protected
the quality and safety of food packaging ink is a major issue of common concern to all mankind, and it is also the main starting point for governments to supervise the food packaging industry, although the means and methods of such supervision may be different. At present, the international practice is to certify the quality and safety management system of ink enterprises. This certification takes the health and personal safety of consumers as the highest purpose, and takes the formulation and implementation of standards as the main link to carry out standardized management and supervision over the whole process of production, storage, transportation and sales of food packaging ink
I. safety and quality control of food packaging ink
in May 2000, more than 50 large retailers and associations around the world jointly launched the global food packaging safety action plan (GFSI), which aims to pay attention to the safety problems in the food supply chain and certify all kinds of food packaging. GFSI certification is the proof that suppliers in the food supply chain comply with the quality and safety standards of food packaging ink. The GFSI guide document consists of three parts: the first part is the requirements of food quality and safety scheme; The second part is the qualified food quality and safety management system, good agricultural practice (GAP), good practice (GMP), good sales practice (GDP) and the establishment of food safety quality control system (HACCP); The third part is the requirements for certification bodies. In addition, GFSI and ISO are jointly drafting the standard ISO22000 related to food quality and safety certification; ISO15161:2001; The guide for the application of ISO9001:2000 in the food and beverage industry has been officially promulgated and has been equivalent to China’s national standard GB /t19080:2003. These situations show that the quality and safety certification of food packaging ink will be carried out faster and more widely, which will bring a greater test of market competition to the ink industry
II. EU certification of food packaging ink
EU certification of dry ink in food packaging production. The dry ink used is consistent with the ink requirements for food packaging in the EU health and safety decree. Certified cyan, magenta, yellow and black inks, as well as the latest transparent dry inks, are mainly used in the field of protective layer or high gloss post-processing. This product was certified by isega, an independent testing agency in Germany last month
isega’s certification method is based on the quality management system of the international standard ISO17025. The official certification shows that the dry ink fully meets the European recommended standards for paper and paperboard in direct contact with food for dry, oily and powdery food
experiments have proved that the use of dry ink for printing by digital printer has no impact on the taste and smell of food contents, and it can reach 100% safety according to EU regulations. All paper and paperboard used for food packaging must pass this certification process and is valid for only two years. The printer is said to be able to print on a variety of substrate materials, including paperboard up to 300 grams thick, which is very suitable for packaging applications
high performance and high quality are fundamental. Diversity and flexibility are very important in the whole value-added service. Passing the EU certification has brought new Oriental one step closer to this goal
Third, packaging inspection promotes the compulsory certification of food packaging
there are many kinds of soft packaging for food and drugs in China. Plastic film, paper, metal and other packaging materials account for a large proportion, accounting for 70% of the total components and adhesives account for 10%; In packaging and printing, ink and other substances account for 20%. In food packaging, the food packaging materials manufactured according to the traditional process are inevitably doped with solvents of harmful substances such as benzene and toluene. A small amount of solvents remain between the composite membranes. With the passage of time, they penetrate into the food from the membrane surface and cause pollution. In addition, stabilizers are added to some plastic products, and these stabilizers are mainly lead stearate, in which the lead salt is easy to precipitate. Once inhaled by the body, it will cause cumulative lead poisoning
at the same time, the packaging safety of food and drugs has attracted increasing social attention. Various packaging safety problems have been exposed one after another. The national quality supervision department has raised the packaging safety to an unprecedented height, and various standards and regulations have been issued one after another. It is reported that China will implement a compulsory product certification management system (i.e. 3C certification) for food packaging products this year. As this will be the first 3C rule in China’s food packaging industry, it has attracted the attention of many food and packaging material manufacturers. Certification is imminent, many negative enterprises have introduced packaging testing instruments to make full preparations for successfully passing the certification and winning the market opportunity
with the rapid development of the food industry, food safety problems are also frequently reported in the newspapers, and a considerable part of them come from the unqualified quality of food packaging. The most fundamental reason for large-scale unqualified packaging is the imperfect market access system, which enables some illegal enterprises to enter the market smoothly. The promulgation of the administrative measures for the certification of food packaging products clearly requires that food packaging materials, especially plastic packaging, paper packaging and composite packaging in the food and beverage industry, must pass the national certification before they can be put on the market, This will play an excellent filtering role in China’s food packaging industry, especially the plastic food packaging industry with low threshold
the physical and mechanical properties of the product do not meet the relevant standards, and the poor barrier property is one of the important factors of unqualified food packaging. In view of this problem, it is imperative to carry out quality inspection and control of food packaging and packaging materials. As a professional manufacturer engaged in the testing and research of flexible packaging ink products in China, New Oriental ink group is famous for its advanced technology, reliable quality and complete product series. It has various flexible packaging testing instruments in line with global standards, which can fully meet the quality control requirements of food and food packaging materials manufacturers. At present, New Oriental is actively paying attention to the relevant testing methods and standards mentioned in the certification management system and its detailed rules, and is willing to enhance exchanges with food manufacturers and packaging and printing manufacturers to help enterprises successfully pass the certification
IV. solvent residue in food packaging
solvent based polyurethane adhesives are mainly used in domestic packaging materials, while solvent based polyurethane adhesives account for only half of the composite adhesives in developed countries such as Europe and the United States. In China, unless the customer requires the use of benzene free ink, it is mainly benzene ink, while developed countries such as Europe and the United States are mainly benzene free ink. The solvent used in solvent based polyurethane adhesive is ethyl acetate, and the diluent during use is also ethyl acetate (it is not ruled out that individual manufacturers may use toluene as diluent to reduce costs), while the ink contains toluene, butanone, ethyl acetate and isopropanol. In order to reduce costs, some manufacturers will use toluene in large quantities. These are just the crux of the problem of solvent residue, which poses a great hidden danger to the safety of packaging
1. It is imperative to snipe at solvent residue in soft bags
composite film packaging bag is one of the fashionable and convenient packaging forms of food. However, packaging safety issues, such as solvent residues, make the market worry about the safety and health of composite film packaging bags unnecessary. The constituent materials of flexible packaging bags are mainly plastic film, aluminum foil, adhesive and ink. Among them, film (including aluminum foil) accounts for about 80% of the total composition, adhesive accounts for 10% and ink accounts for 10%
at present, the problem of excessive benzene content has attracted extensive attention. The solvent residue of film used in flexible packaging industry, such as food, plastic and pharmaceutical composite packaging, has become an unsafe hidden danger. The residual solvents such as benzene, toluene, xylene, butanone, isopropanol and ethyl acetate contained in it do great harm to human body, especially benzene solvents such as benzene and toluene. Benzene and toluene are colorless and strong smelling liquids with strong toxicity, which can cause acute poisoning, paralysis of central nervous system and other hazards. Therefore, the solvent residue of packaging film must be detected
a large number of organic solvents are used in the printing, compounding and coating processes of composite flexible packaging in the production process, such as toluene, xylene, ethyl acetate, butanone, butyl acetate, ethanol, isopropanol, etc. These solvents are more or less residual in composite packaging materials. If packaging materials containing high residual solvents are used to package food and drugs, it will endanger human health
composite packaging refers to the film of printing ink, such as BOPP, pet, etc., which is generally used for food packaging. With the improvement of environmental protection and safety awareness and food packaging (color and taste preservation) requirements in recent years, the quality control requirements for solvent residues in composite packaging bags are becoming more and more strict. Printing and packaging manufacturers and packaging bag users are looking for ways to reduce solvent residues
generally speaking, the solvent residue of composite packaging occurs in ink, solvent and production process. The quality and performance of ink, the drying speed of diluted solvent, the performance of machine, environment and packaging structure will affect the solvent residue. At present, the domestic composite packaging printing is mainly printed by gravure rotary printing machine. The ink is designed to contain benzene and ketones, and the solvent volatilization is the drying method. The ink generally contains different amounts of toluene, butanone, ethyl ester and other solvents. The molecular weight and boiling point of each solvent are different, and the volatilization rate is also different, which forms the reason for the different values of various solvent residues
2. Difficulties in solvent residue control
because flexible packaging products are generally used first
