Food packaging is an important part of the development of the food industry. In the past, people only paid attention to quality when buying food. With the development of the economy, people now also value the quality of packaging. Food packaging directly affects the market positioning standards of food. The food market is an important business scope for plastic bottle packaging manufacturers. The packaging range of food bottles covers: edible oil, soy sauce, vinegar, pickles, dried fruits, candies and jams and other product types. For food bottles, the identification of the production date is extremely important, which gives printer companies a great opportunity. Food bottle inkjet printers have always been based on European and American countries as the leading technology. It was not until 1992 that domestically produced inkjet printers appeared in China. The inkjet printer prints the packaging date on the food bottle, because the food bottle is made of plastic, glass, aluminum, tinplate and other materials. Different materials have different effects on the clarity after printing, and some other materials can easily cause the ink to fall off. This is a problem that food bottle coding manufacturers need to solve. The capacity and specifications of food bottles are large and small, and there are also different differences in coding. This gave birth to different types of food inkjet printers, such as small character inkjet printers, high-resolution inkjet printers, and large character inkjet printers. It is foreseeable that with the continuous development of the food market, food bottle inkjet printers will win more room for development in the future. After more than 20 years of development, with the continuous injection of innovative ideas and high technology in food inkjet printers, it affects the development of the food inkjet printer industry. Good ideas lead the food inkjet printer companies to develop in a better direction.
