Laser Scribing


Almost all packaging foils are so-called multilayered structures consisting of several layers. Different layers  have usually different functions. PET for example makes for stiffness and aroma conservation, PE for sealing and tear resistance, PP for water vapor tightness and aluminum for the general light protection. With easy opening the supporting layer is weakened without affecting other functionalities.


Laser scribing offers excellent solutions using the various optical characteristics of the foil layers. Packaging with laser processed easy opening can easily be opened without tools.
