Food packages are an important part of commodities. In addition to the functions of keeping fresh food and storing and protecting food, you can also use the information on the packaging bag to obtain information about the source of the food, food ingredients, food shelf life, storage conditions, and so on. However, due to factors such as product transportation and contact, ink markings are often prone to "easy to wipe and easy to fall off" problems. At the same time, criminals will erase the date of production of products that are about to expire, and then spray the new production date to continue to be on the market Selling on the market. This will have a great impact on people's health, and also seriously undermine market principles. So how to effectively mark food packaging information? Laser marking can effectively solve this problem.
Laser marking is a method that uses a high-energy-density laser to locally irradiate a workpiece to vaporize the surface material or change the color of the chemical reaction, leaving a permanent mark. It has high accuracy, high speed, and high-speed marking,clear,environmentally friendly and pollution-free. The entire marking information is portrayed on the product packaging, so it is difficult to tamper and counterfeit; and a link database system can be established to allow us to track and query the latest trends of the product in a timely manner. Therefore, the packaging bag uses laser marking to mark the information, such as the date of production, the place of origin of the food, etc .; clear, eye-catching, and permanent do not fall off, erasing will destroy the packaging; and environmental protection, no consumables, and can effectively prevent illegal molecule, providing an umbrella function for public food safety issues.
Laser marking can not only mark information such as production date and food source, but also logo, text, two-dimensional code, barcode and other information. Laser marking is widely used,it can also mark glass bottles, ceramics, tinplate, aluminum plates, cartons and other materials according to different laser wavelengths. In addition, you can also contact Sino-Galvo Tech. to make customized development equipment to customize development according to project requirements to meet the processing requirements of different products. Laser marking is matched with the on-line operation of the production line, which greatly improves the production efficiency and meets the requirements of industrial production. The emergence of laser marking has made up for the lack of traditional processing and helped the transformation and development of the packaging industry.
