Laser marking
Laser marking is a chemical reaction that uses high-energy density laser to locally irradiate the workpiece to vaporize the surface material or change the color, thus leaving a permanent mark As a marking method of long-term marking, it has the characteristics of high marking accuracy, fast speed, clear marking, environmental protection and no pollution. The entire marking information is depicted on the product packaging, so it is difficult to tamper with and counterfeit; In addition, we can also establish a linked database system, so that we can track and query the latest products in time New trends. Therefore, the information marked by the laser marking machine on the packaging bag, such as the production date, food source and other information; Clear, eye-catching and permanent If it does not fall off for a long time, erasing it will damage the package; It is environmentally friendly and has no consumables. At the same time, it can effectively restrain criminals and provide an umbrella for public food safety issues.
Laser scribing
For example, when consumers buy puffed food, the sealing of the packaging bag is not good enough, the contents of the packaging are easy to overflow, and the time limit will be shortened within the validity period. Some seals are too tight, and it is difficult to tear them apart along the dotted line. Therefore, it is difficult to control the strength when opening some food packages. From the perspective of the webmaster consumer, these are all small things that make people headache, However, the laser system of the laser marking machine can select a single film layer in the flexible packaging for marking. In this way, the perfect and easy tearing effect of the flexible packaging is realized, and the integrity of the film can be maintained, so that the outer film is not damaged, so that we can effectively prevent the problems of light exposure and moisture of the goods in the packaging.
On the other hand, aluminum foil layer or other thin films coated with metal layer become a barrier to block the laser from going to other material layers. Therefore, the characteristics of these materials can enable laser technology to accurately locate and scribe the packaging materials. At the same time, the tear line is clearly visible through the human eye, so it is easy for consumers to tear the packaging. Laser scribing and laser drilling technology can effectively prevent the expansion of small holes and avoid the damage to the integrity of the package, and can have good ventilation and moisturizing effects at the same time. We have to be shocked by the amazing technology of laser marking machine.
The wide application of laser marking technology in all walks of life is by no means just talk. For example, it is widely used in electronic industry, aerospace technology, transparent buttons for mobile phone accessories, auto and motorcycle parts, military products, sanitary ware, cosmetics, food packaging, drug packaging, jewelry, craft gifts and other metal and non-metal materials. No doubt, it has been deeply involved in all aspects of your life.
Nowadays, the laser marking process can greatly improve the production efficiency and meet the requirements of industrial production. In today's brand era, the laser marking process can better meet the needs of the times.
