What are the principles and advantages of laser scribing?

The principle of laser marking: only the surface material is damaged, other layers of material are not damaged, and the shape can be adjusted at will with laser marking technology.

Generally applicable to: easy-tear line, easy-tear mouth, easy-to-remove film, easy-to-tear film and other processes.

Advantages of Laser Scribing:

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

2. The line shape of the computer software can be freely edited;

3. The material depth is only micron level;

4. High reliability, no mold loss;

5. High flexibility.

Because composite films such as PET, PP, PE have different absorption and emission wavelengths for CO2 lasers. When one layer of film absorbs laser energy and disappears, the film layers of other materials remain intact. On the other hand, aluminum foil or other films coated with metal layers become a barrier to prevent lasers from entering other material layers. Therefore, the properties of the material will enable laser technology to accurately locate the packaging material. Marking. At the same time, the eyes of the tear line are obvious, so it is easy for consumers to tear open the package. It is worth noting that the laser scribing technology of Laiser is a non-contact and wear-free food packaging process, which can also ensure that the goods will not be damaged during the packaging process, thereby ensuring the stability and reliability of the product.
