Food safety has always been one of the key objects of national concern. In this era of rapid development in which everyone is rushing towards a well-off society. Consumption is uncontrollable, so packaging has always been an area of ​​particular concern for the consumer goods industry, with food safety being 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 the functions of convenient preservation, storage and protection of food, information such as food origin, food ingredients, food shelf life, storage conditions, etc. can also be obtained through the information on the packaging bag. However, ink markings are often prone to problems of easy removal and peeling due to factors such as merchandise transportation and contact. At the same time, some criminals will erase the expired production date of the product, and then spray the new production date to continue to sell in the market. This will have a big impact on people's health and seriously undermine the principles of the market.


 


Laser Marking


Laser marking is the use of a high-energy-density laser to locally irradiate the workpiece, causing the surface material to evaporate or undergo a chemical reaction of color change, thereby leaving a permanent mark. 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 packaging of the product, so it is difficult to tamper and counterfeit; a link database system can also be established, allowing us to track and query the latest developments of the product in time. Therefore, the information marked by the laser marking machine on the packaging bag, such as the production date, the origin of the food, etc.; is clear, eye-catching and durable. If it does not fall off for a long time, it will destroy the packaging if it is wiped; and it is environmentally friendly and has no consumables, and can effectively suppress 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 insufficient, the contents of the packaging are easy to overflow, the aging period is shortened within the validity period, the sealing is too tight, and it is difficult to tear along the dotted line, so it is difficult to control when opening the food packaging. The point of view is a small headache, but the laser system of the laser marker can select individual film layers for marking in flexible packaging. In this way, the perfect tearing effect of the flexible packaging is achieved, the integrity of the film is maintained, the outer film is completely undamaged, and the problems of light and moisture in the packaged goods are effectively prevented.


Laser Scribing


The aluminum foil layer or other metallized film becomes a barrier to prevent the laser from passing through other material layers. The properties of these materials allow laser technology to accurately locate packaging materials and scribe lines. At the same time, the tear line is clearly visible to the human eye, making it easier for consumers to tear open the package. Laser scribing and laser drilling technology can effectively prevent the expansion of small holes, avoid damage to the integrity of the packaging, and have good air permeability and moisture retention at the same time. Must be amazed by the amazing technology of laser marking machine.


Laser marking technology is widely used in various industries, such as electronic industry, aerospace technology, mobile phone keys, automobile and motorcycle accessories, military products, sanitary ware, cosmetics, food packaging, pharmaceutical packaging, jewelry, craft gifts, etc. it. There is no doubt that it has been deeply involved in every aspect of your life.


Today, the combination of laser marking technology and the online operation of the production line 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.
