The date and date of the food packaging bag is the last process before the food leaves the factory. Any regular manufacturer's products are required to be marked with the production date, shelf life, etc. This is an important process related to food safety. And what equipment is used for marking and coding on food packaging? I will introduce it to you today.

The traditional process of marking and coding on food packaging bags is to use ink printing and dyeing technology to print the date, model, pattern, etc. on the packaging. In recent years, with the improvement of food safety requirements, laser technology has gradually replaced ink printing and dyeing technology and has become the mainstream technology for packaging bag coding. Laser marking machines are gradually used in the food packaging industry.

Laser marking of food packaging bags uses a high-energy laser beam to focus on the surface of the product, and burns at high temperature to create patterns and so on. Just set the pattern on the computer, and the software will control the device to run. Laser precise energy control, small heat-affected area, clear and beautiful marking pattern, good touch, corrosion resistance and wear resistance, with significant technical advantages.
