Food safety has always been one of the key objects of national concern. In this era of rapid development where everyone is running towards a well-off society. Consumption is beyond control, so packaging has been an area of special concern for the consumer goods industry, food safety is of paramount importance. Among them, the safety of food packaging bags is particularly important.

Food packaging bags are an important part of the commodity. In addition to the function of facilitating freshness, storage and protection of food, information on the bag can also be used to obtain information on the source of food, food composition, food shelf life, storage conditions, etc. However, due to factors such as commodity transportation and contact, ink markings are often prone to easy removal and peeling. At the same time, some unscrupulous people will erase the production date of expired products and then spray new production dates to continue selling in the market. This will have a great impact on people's health and seriously undermine the market principle.

Laser Marking

Laser marking is the use of high energy density laser on the workpiece for local irradiation, so that the surface material evaporates or the chemical reaction of color change, thus leaving a permanent mark, with high marking accuracy, fast speed, clear marking, environmental protection and pollution-free, etc. The whole marking information is engraved on the product packaging, so it is difficult to tamper and counterfeit; it can also establish a linked database system, allowing us to timely track and Query the latest developments of the product. So the information marked by laser marking machine on the packaging bag, such as production date, food source, etc.; clear, eye-catching and durable. Long time does not fall off, erase will damage the packaging; and environmental protection, no consumables, but also effectively inhibit the lawless elements, to provide the public with an umbrella of food safety issues.

 Laser marking cases

Laser Scribing

For example, when consumers buy puffed food, the lack of sealing of the bag, the contents of the package is easy to spill, the expiration date of the time limit to shorten the seal is too tight, tearing along the dotted line is difficult, so it is difficult to control when opening the food package, standing long consumer point of view is a small headache, but the laser marking machine laser system can choose a separate film layer in the flexible packaging for engraving. This achieves the perfect tearing effect of flexible packaging, maintaining the integrity of the film, leaving the outer film completely undamaged and effectively preventing problems such as light and moisture from the goods in the package.

Laser Scribing

The aluminum foil layer or other metalized layers of film act as a barrier to prevent laser light from reaching other layers of material. The properties of these materials allow laser technology to accurately position the packaging material and scribe the lines. At the same time, the tear line is clearly visible to the human eye, so tearing the package becomes easier for the consumer. The laser scribing and laser punching technology effectively prevents small holes from expanding, avoids damage to the integrity of the package, and allows for good breathability and moisture retention at the same time. One must be astounded by the amazing technology of laser marking machines.

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

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