How to solve coding for frozen food in low temperature environment_Identification Consumables

In order to ensure the freshness of food, frozen food packaging equipment must of course be carried out in a low temperature environment. Therefore, it is necessary to consider whether the inkjet printer ink has excellent adhesion and durability in a low temperature environment. Food and packaging may face temperature changes throughout the supply chain. For example, frozen food may be packed in relatively high-temperature packaging, or warm air may enter a low-temperature production environment. This temperature change combined with moisture in the air may cause condensation on the food before and after coding. There are also manufacturers that store ink in ordinary storage rooms, which are usually much hotter than the production environment. This kind of ink stored at a higher temperature is less viscous than the ink in a printer in a low-temperature production environment. When the printer is running in a low temperature environment, it will be calibrated according to the viscosity of the ink. After adding higher temperature ink, most printers will automatically adjust the ink viscosity to its calibrated viscosity. During this period, as the ink temperature will decrease, the printer will naturally adjust its viscosity. Since these two processes occur at the same time, it may take some time for the ink viscosity to stabilize at the calibration level. Before the calibrated viscosity is reached, performance may be affected, and the quality of coding may decrease. The seemingly minor changes in the production environment may have a serious impact on the effect of the inkjet marking, so the inkjet printer should choose the right ink in a special production environment. Ima inkjet printer adopts non-contact coding technology and uses FDA edible ink, whether it is on soft cake packaging or hard cans, whether it is in high temperature or humidity conditions, or in cold and low temperature production. Under the environment, we can also achieve good printing quality.
