RFH 355nm UV laser is more suitable for marking the date of packaging bags than inkjet printing

Speaking of the current food, many people are more or less worried. Some people are worried that the ingredients are unhygienic, and some people are worried that the food will expire and deteriorate. The editor of RFH Laser often hears reports from the news media that some food workshops have dirty, chaotic, and poor sanitation, and even unscrupulous merchants re-spray expired food with production dates and shelf life dates for refurbishment, which seriously damages consumption. the health of the patient. This is also the disadvantage of traditional inkjet coding. Fortunately, the times are constantly improving, and we have ushered in more advanced laser marking technology.

Compared with the traditional inkjet coding process, the laser marking process is subversive.

The laser marking process does not require any chemicals such as ink. It directly shines a high-energy laser beam on the packaging bag to form a burning mark, which is the mark. This kind of mark can not be wiped off when it gets wet, and it is permanent. This is just a rudimentary mark. We can also mark pattern information such as two-dimensional codes, and accurately manage and supervise the entire series of food production, packaging, delivery and sales through two-dimensional codes, which is what the industry calls a "traceability system". If there is a problem, it can be traced and held accountable through the QR code. For consumers, this is a real quality assurance. It is also good for the environment as it does not require the addition of any environmentally harmful chemicals.

With these obvious advantages, laser marking has become the mainstream process for packaging bag date marking and other markings. And in this mainstream process, nanosecond ultraviolet laser is the mainstream equipment. Next, see the RFH laser editor to give you a detailed explanation.

The nanosecond UV laser of RFH S9-355 series is very popular in the packaging bag date marking processing industry. Its power range is 3.0w-5.0w, and the pulse width is short (<14ns@30K); the beam quality is superior (M2<1.2), which is strictly guaranteed in all frequency ranges; the spot characteristics are perfect (spot ellipticity >90% ). Therefore, it is very suitable for fine marking of materials such as food and pharmaceutical packaging, and because the beam quality is stable enough, it is also especially suitable for high-speed assembly line batch marking processing.

Food safety is no small matter, RFH nanosecond UV laser marking guards the first quality control. Of course, many users who purchase RFH nanosecond ultraviolet lasers are not only used for marking the date of packaging bags, but also for other businesses, because the integrated design of RFH nanosecond ultraviolet lasers has unique Q-switching control technology ( Thanks to the efforts of RFH's doctoral-level R&D team), it is suitable for a variety of laser application control requirements, and one machine with multiple functions.

Technology is the premise, production attitude is the guarantee. In terms of production and assembly processes, we are very rigorous. From procurement, pre-production quality inspection and control, to assembly, finished product testing, warehousing quality inspection, and then to pre-delivery inspection, we strictly control each layer to ensure stable quality. And equipment parameters are consistent with actual operating parameters. Because of this, RFH can supply lasers with excellent performance and service life for the industry, and then win high recognition and good reputation from users from all walks of life at home and abroad, and establish an excellent brand image.
