What is the name of the machine that prints the production date on the plastic packaging
What is the production date printed on the packaging bag
RFH UV laser is used for marking the date on food plastic packaging bags.
I often see many posts discussing on the Internet, "The production date is printed on the food packaged in plastic bags, and the date can be erased by hand in a few days. What is the reason?" or "What material is used for the outer layer of the plastic packaging, spray "The production date of ink can not be erased" and so on.
The former uses ink jet coding technology, which makes the production date easy to be erased, which is an inevitable problem. The latter uses RFH UV laser marking, so it cannot be erased.
Ultraviolet laser marking is to use the laser thermal effect to ablate the surface material of the object, thereby leaving a mark. It has the advantages of non-contact marking, low cost, no consumables, no deformation, no pollution, high speed, high stability, high precision engraving, etc. Therefore, it is widely used in 3C electronic appliances, food plastics and other industries.
In the 13 years of Jinggong, RFH has gradually become a leader in marking food plastic bags through technological innovation and excellent reputation. In recent years, RFH laser has invested a lot of research and development funds in the packaging and printing industry, and made a lot of technical reserves. RFH laser products have brought customers the production process and manufacturing process.
Small size and fast engraving speed are the core of RFH UV laser.
In 2020, for the food plastic bag packaging marking industry, RFH's newly launched S9 series pulsed ultraviolet solid-state lasers are smaller in size, more exquisite in design, more stable in light output, and faster in engraving than similar products. The small and exquisite design means that users do not need to make a large optical path, which can greatly reduce costs, save space, and be lightly installed in the field of flying marking equipment. The S9 ultraviolet laser is not only compact, but also has a more stable cavity structure and stronger scalability than similar products. The same cavity can produce lasers of different powers, and the stability of different power ranges is greatly improved.
Stable quality, long life and durability are important factors for RFH UV lasers to win the hearts of customers.
Short pulse width, superior beam quality and perfect spot characteristics, the booster UV laser is strictly guaranteed in all frequency ranges, and during processing, the heat-affected area is small, avoiding the problems of scorching and deformation; in addition, it is unique The Q-switching control technology is suitable for various laser application control requirements; it also has an internal cavity self-purification system, which makes the laser long life and stable operation.
Behind the stable product quality is backed by a team of professors at home and abroad
RFH adopts a rigorous quality management system mechanism to ensure that from procurement-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, all levels are checked to ensure stable quality and equipment parameters Consistent with actual operating parameters. Independent research and development of the laser dedicated power control system, which can update the power control system functional modules in time, and improve the functional modules according to the needs of the laser.
Even under the extreme conditions of industry and scientific research, each UV laser developed and produced by RFH maintains consistent and stable quality, constant beam quality, high-efficiency power consumption characteristics, and excellent cost performance and high reliability, winning all walks of life at home and abroad. Industry users are highly recognized and have a good reputation.
