355nm UV laser marking food packaging QR code production date

 

During this special Spring Festival, many people stopped visiting or gatherings. However, the family has to live the life of firewood, rice, oil, salt, ginger, vinegar and tea. We still have to go to the market to buy vegetables and go to the mall to prepare dry food, so we still have to face the problem of how to choose products.

More and more cases make us begin to pay attention to food safety issues. Whether the source of food is regular and whether the production process is regular are all issues we have to consider. When we buy goods, we can find the answers to the questions on the outer packaging. The laser markings on the outer packaging, production date, production batch number, two-dimensional code, etc., all record those answers, and consumers can verify the authenticity by looking and scanning. Here, RFH Laser advises consumers to choose products with such marking information as much as possible.

 

For product packaging laser marking manufacturers, RFH recommends that you choose to use RFH's high-quality UV laser-355nm UV laser. The help it brings to manufacturers is multi-layered.

 

1. The marking effect is more refined

RFH 355nm ultraviolet laser has a short pulse width (<20ns@30k), a small heat-affected area during processing, and superior beam quality (M2<1.2). It is strictly guaranteed in all frequency ranges and has perfect spot characteristics (spot ellipticity>90 %), therefore, it is so simple to complete high-precision marking tasks.

 

2. Faster marking speed and higher efficiency

In just 1 second, the RFH laser can process and mark several production dates and production batch numbers, with fast speed and high stability, and the assembly line can achieve high-speed and efficient processing and production.

 

Third, reduce production costs

The RFH laser contains an internal cavity self-purification system, so the laser has a long life and durability. In addition, it also has a unique Q-switching control technology, which can be suitable for various laser application control needs. It has multiple functions and simple operation to meet the manufacturers' multiple production application needs. In the long run, it can reduce the construction cost of a large number of new production lines for manufacturers. Really save worry and effort.

 

The importance of the production date of food products is self-evident. The use of RFH laser for laser marking is more secure and more secure.

 

RFH has been based in the nanosecond laser industry for 12 years. After 12 years of hard work, it has accumulated strong technical strength, enabling laser products to maintain consistent stable quality, constant beam quality and under extreme conditions in industry and scientific research. The characteristics of high efficiency and durability have won the high recognition and good reputation of domestic and foreign industry users.
