Laser scribing technology for composite films

Laser scribing technology is an advanced and flexible technology that focuses the laser energy on the film layer to be scribed without damaging the entire film. Advantages: easy to disassemble and assemble, laser scribing and punching technology.

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

2. The shape of the scribing can be freely selected;

3. Only a small amount of wear;

4. High reliability.

Because composite films such as PET, PP, and PE have different absorption and emission wavelengths for CO2 lasers, when one layer of film absorbs laser energy and disappears, the other material film layers are 100% intact and undamaged. 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 this material will enable laser technology to accurately locate and mark the packaging material. At the same time, the tear line is clearly visible to the human eye, so it is easy for consumers to tear open the package. This shows that it is worth noting that laser marking technology is a contactless and wear-free process for food packaging, so it can also ensure that the goods in the package will not be damaged during the packaging process, thereby ensuring the stability and reliability of the product.
