    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.
