In recent years, the news has exposed many unscrupulous merchants who tampered with the production date privately. Most of the unscrupulous merchants have grasped the "Ink printing production date, as long as it is wiped lightly with alcohol or thinner, it will fall off and eliminate." A business opportunity, play the "date game", wipe off the production date on the food packaging bags that have expired or will expire, and then use an inkjet printer to reprint the production date before selling.

These severely affected the brand image and sales volume of the manufacturer. However, then again, this kind of problem occurs, and the main source is still caused by the irregular production process within the production enterprise. During production, if an inkjet printer is used, the production date printed on it can be easily altered. If the laser coding machine (ie, laser marking machine, laser engraving machine, laser engraving machine) is used, the production date mark cannot be altered or removed. It is durable and cannot be wiped. The environmental relationship (touch, acid and reduced gas, high temperature, low temperature, etc.) or time disappears for a long time. The markings made by the laser coding machine have fine patterns, clear and beautiful patterns, and good feel.

Once the mark is marked, it cannot be changed. And erasure, can better guarantee the quality of the goods, and make some illegal vendors can not take advantage.

The online flying laser coding machine produced by Foshan Fulan Laser is a high-tech product developed and designed specifically for the marking of product packaging in various industries on the assembly line. According to the different needs of customers, it can be equipped with optical fiber, green light, mopa, CO2, UV and other lasers, which can be combined with the assembly line workbench to realize assembly line operation and automatically identify the position of the product to be marked, thereby achieving high-speed and accurate marking. Not only can improve production efficiency, but also improve the overall grade of the product. The laser coding machine can help you easily solve the problem of tampering with the production date.
