The application and value of laser marking equipment in the food packaging industry

Food safety has always been one of the key objects of national concern. In this era of rapid development where everyone is rushing towards a well-off society. Consumption is uncontrollable, so packaging has always been an aspect of special concern in 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 the functions of convenient preservation, storage and protection of food, information such as food source, food ingredients, food shelf life, storage conditions, etc. can also be obtained through the information on the packaging bags. However, due to factors such as commodity transportation and contact, ink markings are often prone to problems of easy removal and falling off. At the same time, some lawless elements will erase the expired product production date, and then spray a new production date to continue selling it on the market. This will have a great impact on people's health and seriously undermine market principles.

Laser marking

Laser marking is the use of high-energy-density lasers to partially irradiate the workpiece, causing the surface material to evaporate or undergo a chemical reaction that changes color, thereby leaving a permanent mark. It has the characteristics of high marking accuracy, fast speed, clear marking, environmental protection and pollution-free. The entire marking information is engraved on the product packaging, so it is difficult to tamper with and counterfeit; a linked database system can also be established to allow us to track and query the latest developments of the product in a timely manner. Therefore, the information marked on the packaging bag with a laser marking machine, such as the production date, the origin of the food, etc., is clear, eye-catching and lasting. It does not fall off for a long time, and wiping it off will destroy the packaging; it is also environmentally friendly and has no consumables, and can effectively suppress lawbreakers, providing a protective umbrella for public food safety issues.

Laser Scribing

For example, when consumers buy puffed food, the packaging bag is not sealed enough, the packaging contents are easy to overflow, the validity period is shortened, the seal is too tight, and it is difficult to tear along the dotted line. Therefore, it is difficult to control when opening the food package. From the perspective of the webmaster consumer, it is a headache. However, the laser system of the laser engraving machine can select a separate film layer in the soft package for engraving. In this way, the perfect tearing effect of the soft package is achieved, the integrity of the film is maintained, the outer film is completely undamaged, and the problems of light and moisture in the package are effectively prevented.

The aluminum foil layer or other metal-coated films become a barrier to prevent the laser from reaching other material layers. The characteristics of these materials enable laser technology to accurately locate the packaging material and scribing. At the same time, the tear line is clearly visible to the human eye, so it is easy for consumers to tear open the package. Laser scribing and laser punching technology can effectively prevent the expansion of small holes, avoid damage to the integrity of the package, and have good air permeability and moisture retention at the same time. One must be shocked by the amazing technology of the laser marking machine.

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

Nowadays, the combination of laser marking technology and online operation of the production line can greatly improve 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.
