Food packaging film marking, using RFH 355nm ultraviolet laser
3W UV laser marking food packaging film without burning
Ultraviolet laser high-definition marking food packaging film
RFH has a mature professor and doctoral level R&D team. With 13 years of experience in marking technology, the 355nm UV laser developed and produced has the characteristics of fast speed, high precision and high stability.
Food is the priority for the people, and food safety has always been an issue that the State Supervision Bureau attaches great importance to. In 2020, all aspects of domestic food safety will be raised to a new level, and the use of lasers for standardized, healthy, and traceable food packaging is possible Ushered in an explosive growth.
Food safety brings great trouble to our lives. The food must be strictly guarded. Therefore, the application of new technologies such as laser marking in the food industry has become inevitable.
Advanced application of laser technology in food packaging that has been criticized
Lasers, computers, atomic energy, and semiconductors are collectively referred to as the four great inventions of mankind in the 20th century, and now they play an important role in the fields of anti-counterfeiting, packaging and printing. It promotes the modernization of the packaging and anti-counterfeiting printing industry. Laser coding, laser cutting, laser drilling, packaging marking, laser anti-counterfeiting, the list goes on.
Laser coding technology
The paintable modification of the production date of the product has been criticized by the majority of people. Many foods and drugs are returned to the oven after the expiration date and the production date is changed before being sold on the market. The practice of small workshops also caused many big factories to suffer unjustified injustices. The application of UV laser marking in the food and drug industry makes it impossible to alter the production date of food and drugs. Not only makes food and medicine safer, but also makes manufacturers and consumers more trustworthy. Ultraviolet laser marking is indelible, as long as the surface of the object is not severely damaged, the marking content cannot be destroyed. At the same time, marking uses non-contact marking, so the object itself will not be damaged.
Compared with other competitive technologies, laser coding technology has become a general packaging coding method in today's market. Many marking and coding applications are suitable for laser coding technology, and the market is ready to convert its coding needs to laser technology. Currently, more than 50% of existing coding applications can use laser coding. In addition, the original coding application materials and online speed are completely matched with laser coding without any adjustment. Laser coding greatly reduces production costs while increasing the overall output.
Laser scribing technology
In addition, laser technology can select a single film layer in flexible packaging for scribing. In this way, the perfect and easy-to-tear effect of the flexible package is realized, and the integrity of the film can be maintained, so that the outer film is intact, so as to effectively prevent problems such as light and moisture in the package.
Today’s advanced laser technology is completely capable of scoring in free combinations. For example, many snack packages currently use a design style of scoring in accordance with the outline of the printed pattern on the package. This scribing method is laser scribing. The advantage lies in. Laser drilling technology
In addition, when the packaging tape needs to have holes, the laser system can perforate the packaging for "ventilation and preservation". This is the current technology in the world. Perforation can increase the shelf life of the goods in the package, or cater to the product after being heated by a microwave oven. Pressure on food packaging. Now, the laser perforated line has been able to achieve the effect of tearing the entire package along the dotted line.
[RFH Laser Seiko 13 years] In the fierce market competition, only by continuous technological innovation and excellent quality reputation will we go for a long time. RFH is one of the leaders. 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.
The UV lasers and green lasers mainly used by RFH in the marking market of the packaging industry have met the needs of customers with excellent stability and have been widely used in the packaging industries of food, medicine and cosmetics.
One of the recommended models: Expert Ⅱ 355nm UV laser
The power range of Expert Ⅱ 355 series UV diode pumped pulsed solid-state lasers is 3w~12w, with short pulse width (<14ns@30K), superior beam quality (M2<1.2) and perfect spot characteristics (spot ellipticity) >90%).
Recommended model two: K-6 4W-6W UV pulsed solid-state laser integrated machine
The K-6 series water-cooled UV diode pumped pulsed solid-state lasers developed and produced by RFH have a power range of 4W to 8W. It has a short pulse width (<20ns@30K), superior beam quality (M2<1.2) and perfect spot characteristics (spot ellipticity>90%). This series of lasers is particularly suitable for ultra-fine processing of high-end markets, mobile phone shell parts, cosmetics, medicines, food and other polymer materials packaging bottle surface marking; PCB board marking, LCD liquid crystal glass, glassware surface, metal surface coating, plastic Buttons, electronic originals, gifts, communication equipment, building materials and many other fields.
As the world’s second largest economy and a country with a large population, demand will be a huge market that is rising rapidly. For food packaging printing, it is not only necessary to meet safety requirements in terms of production capacity, but also to use advanced lasers to control safety links. Enhance the public's solution to the problems of identifying the shelf life of food and tracing the source.
