Advanced application of nanosecond solid-state laser in food packaging laser technology

Food is the most important issue for the people, and food safety has always been an issue that the State Supervision Bureau attaches great importance to. Especially after the baptism of this epidemic, it is expected that all aspects of food safety in the country will be raised to a new level, and the use of lasers for standardization and health , Traceable food packaging may usher in an explosive growth.

Food safety has brought great troubles 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 permanent and indelible, as long as the surface of the object is not severely damaged, the marking content cannot be destroyed. And since the non-contact marking is used while marking, it will not damage the object itself.

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 speeds can be 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 most advanced technology in the world. Perforation can increase the shelf life of the products in the package, or cater to the product being microwaved. The pressure on food packaging after heating. Now, the laser perforated line has been able to achieve the effect of tearing the entire package along the dotted line.

The K-6 series of water-cooled UV diode pumped pulsed solid-state lasers developed and produced by Ruifengheng 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. Enhancing the public's solution to issues such as identifying the shelf life of food and tracing the source.
