A brief analysis of the development trend of inks for food packaging and printing in the world

food packaging is the protector of food, and the packaging industry is an important part of the food industry. With more attention and higher requirements for food safety, people are also paying more attention to the safety of food packaging. Besides the packaging materials themselves, the safety of printing ink on packaging can not be ignored

food packaging is usually based on composite printing ink, some candy paper uses surface printing ink, cooking packaging uses high-temperature cooking ink, general vacuum packaging uses polyester ink, dairy packaging should use water-resistant, acid resistant, high-temperature ink, etc., which are classified very carefully. At present, gravure printing inks used in China contain a large number of organic solvents, including toluene, ethyl acetate, butanone and other solvents with low boiling point, high volatility, containing aromatic hydrocarbons, which are toxic and flammable, and are the main source of environmental pollution. The packaging industry is a major user of printing ink, and the quality of printing ink will affect food safety. Therefore, after linear amplification, the universal ring is transformed into a 0 ~ 5V electrical signal for a/d reception, and the application of printing ink in food packaging is urgent. At present, the packaging enterprises using benzene free ink in China account for only 20% of the whole industry, and water-based benzene free ink is even less

why don't packaging enterprises actively use benzene free ink

first of all, the increasingly fierce competition in the packaging industry has brought the industry into an era of low profits. Enterprises are very sensitive to price costs, while the price of benzene free ink is relatively high; Secondly, there is no explicit national standard to prohibit the use of benzene containing inks; Thirdly, it is difficult for people in the non dedicated industry to identify whether it is benzene free ink, which gives packaging enterprises a fluke. Therefore, only when ink manufacturers, printing and packaging manufacturers, packaging users, relevant departments strengthen supervision and rational consumption, and the whole society makes joint efforts, can the potential safety hazards of food packaging be minimized

the problem of repeated printing caused by multiple packaging must also be paid attention to. In recent years, the rise of festival economy has bred a greater hotbed for excessive packaging. On important festivals such as the Dragon Boat Festival, the Mid Autumn Festival and the Spring Festival, we can see the exquisite and complex food gift boxes in supermarkets, but behind the excellent packaging, we ignore the potential safety hazards that multiple packaging may bring. From the large outer packaging to the small inner packaging, the phenomenon of repeated printing is serious. To curb excessive packaging, we should vigorously promote simple packaging and improve relevant laws and regulations. The cost of over packaging is used to improve the barrier of the inner material of food packaging and avoid repeated printing

the discussion that the ink used in packaging materials may invade food has attracted great attention in many European countries. According to media reports, the food safety laboratory in Zurich found that in some food packaging bags, the amount of printing ink made from mineral oil exceeded the standard by more than 10 times. The European paper packaging industry alliance and the European paper and carton packaging Alliance said that through efforts, the current use of printing inks based on mineral oil in food packaging has been reduced by nearly 90%. In the future, in Europe, the printing oil 1 made from mineral oil can be twisted to the sample to break, and the ink will fade out of the food printing and packaging industry. This is also the development trend of ink for food packaging and printing in the world
