The solution of Bote ultraviolet Laser marking machine in food packaging industry
Food safety has always been one of the key objects of national concern. In this era of rapid development in which everyone rushes to a well-off society. Consumption has been irresistible, so in the field of consumer goods industry, packaging has been a special concern, and food safety has been listed as the top priority. Among them, the safety of food packaging bags is also particularly important.
Food packaging bag is an important part of commodity. In addition to the functions of preservation, storage and protection of food, it can also obtain the information of food source, food composition, shelf life and storage conditions through the information on the packaging bag. However, due to the factors of commodity transportation and contact, ink marks are often easy to be "easy to erase, easy to fall off"; At the same time, some criminals will erase the production date of the products that are about to expire, and then spray a new production date to continue to sell in the market. This will have a great impact on people's health, but also seriously damaged the market principles.
Today, laser technology can provide a good solution:
Laser marking is a kind of marking method, which uses high energy density laser to irradiate the workpiece locally to vaporize or change the color of the surface material, thus leaving a permanent mark. It has the characteristics of high precision, high speed, clear marking, environmental protection and no pollution. The whole marking information is depicted on the product packaging, So it is very difficult to tamper and counterfeit; Moreover, it can also establish a linked database system, so that we can track and inquire the latest trend of products in time. Therefore, the information marked by the Laser marking machine, such as the date of production, the source of food and so on, is used for packaging bags; It is clear, eye-catching and permanent, and the package will be damaged if it is erased; And environmental protection, no consumables, but also can effectively inhibit lawless elements, provide an umbrella for the public food safety issues.
For example, when consumers buy puffed food, the sealing of the packaging bag is not good enough, the contents of the package are easy to overflow, and the time limit will be shortened within the validity period. Some seals are too tight, and it is hard to tear along the dotted line. Therefore, it is difficult to control the strength when opening some food packages. Considering these from the perspective of stationmaster consumers, it is a headache, But 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 flexible packaging can be realized, and the integrity of the film can be maintained, so that the outer film can not be damaged, so that we can effectively prevent the emergence of problems such as light and moisture of goods in the package.
On the other hand, aluminum foil or other thin film coated with metal layer becomes a barrier to prevent laser from leading to other material layers. Therefore, the characteristics of these materials can make the laser technology accurately locate and mark on 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 marking and laser drilling technology can effectively prevent the expansion of small holes and avoid the damage to the integrity of packaging, and can have good ventilation and moisturizing effect at the same time. We have to be shocked by the amazing technology of Laser marking machine.
Laser marking technology is widely used in all walks of life, such as the application in electronic industry, aerospace technology, light transmission button of mobile phone accessories, spare parts of automobile and motorcycle, military products, sanitary ware, cosmetics, food packaging, drug packaging, jewelry and so on All kinds of metal and nonmetal materials such as craft gifts are widely used. No doubt, it has been deeply involved in all aspects of your life.
Nowadays, the laser marking process with the production line online operation, can greatly improve the production efficiency, adapt to the requirements of industrial production. In today's brand era, laser marking technology can better meet the needs of the times.
