Technical Analysis of Frozen Food Coding and Marking Scheme_Marking Consumables
Frozen food is the preservation of food at a temperature below the freezing point after being frozen. There are many kinds of frozen food. The most common daily products are meatballs, glutinous rice balls, shrimp rolls, crab sticks, steaks, pork chops, deep-sea fish, etc. Most of these frozen foods are mainly packaged in plastic. Food products need to mark the production date, shelf life, batch number and other information on the packaging. Most of the packaging of frozen processed products is small plastic packaging, labelling is not realistic, production efficiency is low, and the image is not generous enough. Small-character inkjet printers are used when the most commonly used labeling scheme is required for the labeling of frozen food packaging. The small character inkjet printer is mainly dot matrix inkjet, the ink dries instantly, and the inkjet on the plastic packaging is scratch-resistant and wear-resistant, beautiful and generous, and improves the brand image very well. The coding speed is very fast, and it can be used in conjunction with the production line, or it can work on a separate assembly line. Frozen food can be marked before and after sealing. In the actual application process, due to the different materials of the plastic packaging bags, although the small character inkjet printer with better ink adhesion is used, it is inevitable that the code may be dropped. The specific solutions mainly include the following two methods: coding before entering the cold storage. In the case of code loss when out of the warehouse, it must be replaced with a special frozen ink that can adapt to sudden changes in temperature. Ensure the adhesion of the ink. After leaving the warehouse, the code will be dropped. The main reason is that the surface of the packaging bag has returned to frost and water due to the change in the external environment. At this time, we need to do the defrosting and dewatering steps before coding and replace it with the corresponding The corresponding ink is fine.
