A brief discussion on the application of laser marking machines in food packaging bags

Food packaging bags are an important part of the product. In addition to facilitating preservation, storage and protection of food, food packaging bags can also be used to obtain the source of food and food ingredients through the information on the packaging bags.

Food packaging bags are an important part of the product. In addition to functions such as convenient preservation, storage and protection of food, you can also obtain information on the food origin, food ingredients, food shelf life, storage conditions and other information through the information on the packaging bags. However, due to factors such as product transportation and contact, ink marks are often prone to “easy to erase and fall off” problems; at the same time, there are also criminals who will erase the production date of the product that is about to expire, and then spray a new production date to continue in the market. This will have a great impact on people’s health and seriously undermine market principles. So how to effectively mark food packaging information? Laser marking machines can effectively solve this problem.

Laser marking uses high-energy-density laser to locally irradiate the workpiece to vaporize or produce surface materials.
A marking method that causes a chemical reaction of color change to leave a permanent mark. It has the characteristics of high marking accuracy, It has the characteristics of fast speed, clear marking, environmental protection and no pollution. The entire marking information is engraved on the product packaging. Therefore, it is difficult to tamper and counterfeit; and a linked database system can also be established to allow us to track and counterfeit in a timely manner. Check the latest product trends. Therefore, packaging bags use laser marking machines to mark information, such as production date, Food origin and other information; clear, eye-catching, permanent and will not fall off, erasing will damage the packaging; and environmentally friendly,
There are no consumables, and it can also effectively suppress criminals and provide a protective umbrella for public food safety issues.
