In the era of zero-tolerance food safety, ink printing will eventually exit!

The conventional method for marking on the packaging is to use ink to print the code. The ink used in this ink jet printer is mainly composed of methyl ethyl ketone, thinner and cleaning agent. Butanone is easily volatile and slightly toxic, and the smell is relatively unpleasant. On the one hand, it is not good for the health of the operators. On the other hand, it is easy to fall off when printed on the packaging surface, which poses certain safety risks, especially on the surface of food packaging. The market's demand for indelible marking and avoiding ink contamination is increasing, and new marking techniques are needed to apply to the packaging and coding process. Therefore, laser marking machines are becoming more and more recognized by customers as new marking tools. Keming Noodle Industry is a leading company in the production of dried noodles in China. It only produces all kinds of noodle products. The packaging materials are mainly PE film and carton packaging. The contact surface between the dried noodle product and the package is larger, and once opened, it is extremely easy to be contaminated by the package if it is not used up. The early packaging marks of dried noodles will also be contaminated with odor. Taking into account many factors, Keming Flour Industry adopted the manufacturer's Flying Series laser marking machine. The manufacturer combined with Keming's needs, integrated a 3W ultraviolet laser into the product line, using a specially customized galvanometer and F-θ lens, and standard touch screen equipment, which is easy to install and flexible to operate. With the assistance of the manufacturer’s technicians, the installation was quickly completed, and Keming’s employees quickly acquired new skills and achieved a perfect cooperation with the new colleague, the laser marking machine! Kepeng Flour Industry adopts Feidong series laser marking machine on-site new marking equipment after entering the workshop, the workshop is quiet and tidy, with a completely new look. The third phase is marked, the pure speed reaches 10-20 m/min, and the whole process is orderly. The mark is accurately printed on the color of the seal, the effect is clear, can not be erased, and does not produce smoke, non-toxic and harmless. In addition to Kepeng, domestic noodle companies include Jinshahe, COFCO, Arowana, etc. These companies also produce other seasoned foods or staple foods, with similar packaging materials. As an important direction of laser application, laser marking machine is a common processing method in many fields. Its unique process not only makes the product packaging more exquisite, but also has many advantages such as higher marking efficiency and good anti-counterfeiting effect. In the laser + era, laser marking machines will eventually become the protagonist in the field of food packaging. Because in a modern society where consumers have zero tolerance for food safety, safe and pollution-free processing methods are the general trend!
