  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.
