Laser scribing technology provides good reputation for food packaging industry

Speaking of laser scribing, many people may not know it, but it is actually closely related to our lives. When you walk into a market supermarket or enter the snack area, you can see a lot of laser scribing processes. The biggest advantage of laser scribing is that it can tear open the package smoothly and completely along the route set by the package, and the entire package will not be spilled due to excessive force, which greatly affects the brand effect.

Laser scribing technology is a more advanced and flexible technology. Laser scribing technology concentrates the laser energy on the film layer that needs to be marked without damaging the entire film. Advantages of laser scribing and punching technology: easy-to-tear packaging

Laser scribing and laser punching technology effectively prevent the expansion of small holes and avoid damage to the integrity of the package, and can also have good ventilation and moisturizing effects.

Laser processing includes cutting, scribing, drilling or structural manufacturing. Laser processing must not only be fast and precise, but also maintain high throughput - therefore, the application of lasers to industrial manufacturing also faces many challenges. The laser industry is constantly innovating to further optimize the processing technology and ensure high-quality processing.

1. Only the selected film layer is marked, and other film layers are not affected;

2. The shape of the marking line can be freely selected;

3. Only a small amount of wear and tear occurs during the production process;

4. High reliability.

For example, the composite film PET, PP or PE, the absorption and emission of carbon dioxide laser wavelength have different characteristics. Therefore, when one layer of film absorbs the laser energy and disappears, the film layers of other materials remain 100% intact. On the other hand, the aluminum foil layer or other film coated with the metal layer has become a barrier to prevent the laser from entering the other material layers. Therefore, the characteristics and markings of these materials can be accurately located. At the same time, the tear line can be clearly seen by people's eyes, so consumers can easily easy to tear packaging. Therefore, it is worth noting that laser scribing technology is a non-contact and wear-free food packaging process, which also ensures that the goods will not be damaged during the packaging process, and ensures the stability and reliability of the goods.
