Food safety is one of the key objects of national concern. In this era of rapid development when everyone is heading towards a well-off society. Consumption is unstoppable, so packaging has always been a particular concern of the consumer goods industry, and food safety is the most important. Among them, the safety of food packaging bags is particularly important.


Food packaging bags are an important part of commodities. In addition to facilitating preservation, storage and protection of food, information on food sources, food ingredients, food shelf life, storage conditions and other information can also be obtained from the information on the packaging bag. However, due to factors such as commodity transportation and contact, ink marks are often easy to erase and fall off; at the same time, some criminals will erase the production date of the product that is about to expire, and then spray the new production date to continue on the market Sales. It has a great impact on people's health, and it also severely undermines market principles.


Now, laser technology can provide a good solution:

Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece to vaporize or discolor the surface material, thereby leaving a mark. It has the characteristics of high marking accuracy, fast speed, clear marking, environmental protection and pollution-free. The entire marking information is portrayed on the product packaging, which is difficult to tamper with and counterfeit; and a link database system can be established to allow us to track the trend of the product in time. Therefore, packaging bags use UV laser marking machine to mark the information, such as production date, food source, etc.; clear, eye-catching, does not fall off, wiping off will destroy the packaging; moreover, environmental protection, no consumables, can effectively restrain criminals, and provide food for the masses Security umbrella is provided.


For example, when consumers buy puffed food, the sealing performance of the packaging bag is not good enough, the packaging content is easy to overflow, and the timeliness within the validity period will be shortened. Moreover, some seals are too tight and difficult to tear along the dotted line, so it is difficult to control the strength when opening some food packages. Webmasters and consumers think these are trivial headaches, but the laser system of the UV laser marking machine can choose a separate film layer in the flexible package for marking. In this way, the tearing effect of the flexible package is realized, the integrity of the film is maintained, and the outer film is intact, thereby effectively preventing the goods in the package from being exposed to light and moisture.


On the other hand, the aluminum foil layer or other metal-plated film becomes a barrier to prevent the laser from passing to other material layers. Therefore, the properties of these materials enable laser technology to accurately locate and scribe packaging materials. At the same time, the tear line is clearly visible by the human eye, so it is easy for consumers to tear the package. Laser scribing and laser perforation technology can effectively prevent small holes from expanding, avoid damaging the integrity of the package, and at the same time have a good breathable and moisturizing effect. We have to be shocked by the amazing technology of the UV laser marking machine.


Laser marking technology is widely used in various industries, such as the electronics industry, aerospace technology, mobile phone accessories, transparent buttons, auto and motorcycle accessories, military products, sanitary ware, cosmetics, food packaging, pharmaceutical packaging, jewelry, craft gifts, etc. There is no doubt that it has been deeply involved in all aspects of your life.


Nowadays, the laser marking technology is matched with the online operation of the production line, which can greatly improve the production efficiency and meet the requirements of industrial production. In today's brand era, laser marking technology can better meet the needs of the times.
