3W5W UV laser marking production date on food packaging bags and cartons
Food packaging bags are an important part of food products. In addition to being able to design different styles on the outer packaging to promote products, they can also protect food from contamination. The outside of the food packaging bag needs to be marked with the date and production information according to the requirements and standards. The marking method of the RFH UV laser makes the marking more convenient and efficient.
RFH UV laser tells you how the production date on the food packaging bag is printed
The difference between RFH UV laser marking and traditional ink jet marking is that UV lasers change the contact marking method, and use non-contact marking to radiate small light spots. Ultraviolet laser has the characteristics of short pulse, high beam quality, high peak power, etc. It is a low-temperature cold light source, and has little thermal impact during marking, and it will not damage or scorch materials such as plastics that are more sensitive to heat.
355nm UV laser marks the date on food plastic packaging bags safely and without pollution
The RFH UV laser has fast compliance speed, high efficiency, and long continuous use time, and there is no problem such as the need to replace the ink midway like the traditional ink marker. Because it is not suitable for ink consumables, RFH UV lasers are safer, more environmentally friendly and reliable in use. The graphic information to be marked can be changed at will, which meets the needs of daily replacement date on food packaging bags. The marked information The characteristics of never fading also occupy an absolute advantage.
The RFH UV laser is produced in a dust-free workshop and will not produce any pollution during the marking process. It is a truly green and environmentally friendly high-tech product.
