Can the high-temperature hot ink roll be printed on the packaging bag to ensure that it will not fall off after high-temperature sterilization?

The use of hot ink roll and ink coding machine to print the production date is widely used in the food industry.

The production date printed by the solid ink roller is mostly used in food plastic bags. This is because many plastic bags are generally re-sealed after packaging the product. It is convenient and clear to install an ink coding machine on the sealing machine to print the production date. However, some products have to be sterilized by high temperature after sealing. Can the date printed by coding machine at this time be resistant to the process of high temperature sterilization?

Because different food factories have different sterilization processes, some use the pasteurization process temperature of about 100 degrees, while some use high-temperature sterilization temperature can reach 121 degrees, the date printed by different hot ink roll can withstand different temperatures also show different results.

The high temperature cooking hot ink roll can generally withstand the temperature of food pasteurization, but it cannot withstand the process of high temperature sterilization. This is because the hot ink roll also needs to dissolve the solid ink at a certain temperature and then transfer it to the food bag during the printing process. Therefore, if the tolerance temperature of the hot ink roll is higher than the sterilization temperature of the food packaging bag, the printing marks of the hot ink roll will fall off during the production process.

UNIONCODING's high temperature cooking hot ink roll has the characteristics of ultra-high temperature resistance. High temperature hot ink roll refers to the hot ink roll of the hot ink roll coding machine with good adhesion, sassafras resistance, cooking resistance, high temperature resistance and clear printing. The high-temperature hot ink roll should have good adaptability to the printed material, and still have clear handwriting and good sassafrass resistance after high-temperature sterilization. Generally, similar hot ink roll products will appear blurred or even fall off after high temperature sterilization. In the biscuit production workshop, due to the high ambient temperature of the workshop, generally similar hot ink roll products are easily rubbed off.

UNIONCODING product category and introduction
