Today, with the increasing attention to food safety, important information on food packaging bags is strictly required to be printed and painted in accordance with relevant regulations. In the past, ink spraying was often used to mark important information such as the production date and shelf life of food, but many problems were also found.

How to spray the date on the edge of the plastic bag? RFH UV laser will not lighten the color

Mr. Huang from Lu'an discussed this issue in depth when he visited the RFH production line. The traditional spraying process is easy to produce unclear and incomplete spraying. Because food packaging bags are generally small in space, it is difficult for the ink nozzle to accurately spray relevant information on the edge of the packaging bag. Moreover, due to different transportation or storage conditions, it is easy to cause the ink to become lighter, discolored or even disappear.

With RFH 355nm UV laser, you no longer have to worry about unqualified food packaging bags

Mr. Huang's factory has suffered a lot in this regard. Due to technical limitations, the food packaging bags produced were not sprayed with relevant information as required and were fined by the Food and Drug Administration. That's why he came to RFH.
After Mr. Huang visited RFH's production line and product demonstration, he immediately decided to cooperate with RFH. Mr. Huang said that RFH's UV laser is exactly what they need, because this device can accurately print information on the edge of food packaging bags, and no matter how small the space is, as long as it is set up on the computer, there will be no mistakes in spraying. . Moreover, the persistence of laser spraying information is not affected by the external environment, and there will be no discoloration and lightening.

With RFH's UV laser, they no longer have to worry about producing non-compliant food packaging.
