How they can be scribed for laminates?
Laminates with Aluminium Layer - The metal layer (> 4µm thickness) works as natural barrier for the laser power
- The threshold to damage aluminium or the layer below is high >> safe & reliable process
- A paper layer absorbs a high amount of laser power
- Metallization (< 4µm thickness) is likely to be removed in the laser process
- A metal layer requires significant higher laser power for perforation

Scribing of Laminate without Aluminium Layer
Laminates without Aluminium Layer - No natural barrier exists to limit the scribing depth.
- Differences in absorption rate of each layer define the barrier (scribing depth) for the laser beam• Laser power stability is crucial for a constant quality
- The scribing depth within one layer can not be guaranteed.
- The better absorbing layer will be scribed >> Select the best wavelength
- The thickness of the film defines the necessary laser power for perforation.

Laser for Easy Open Packaging
Easy open packaging is a preferred product in the flexible packaging industry because of its convenientandclean-tear capabilities. Our advanced laser process ensures a precise and consistent tear that maintainstheintegrity of the package. Advantages of Laser Scoring for Easy Open Packaging - Precise, clean and consistent tear along scored line
- Controlled score depth and tear propagation
- Offers both straight and contoured patterns and shapes
- Maintains barrier properties
- In registration with print • Eliminates need for knife or scissors to open
- Aesthetic appearance of package unaffected
- Effortless functionality resulting in consumer satisfaction
Easy open features can be utilized on a variety of packaging
such as stand-up, press-to-close zipper and slider pouches, pour spouts, stick packs, and zipper bags. These features
can also be used in peel & reseal, and microwavable applications.
