automotive industry and home entertainment – lasers are used everywhere. In the converting and paper processing industry usually high power CO2 laser sources are used. As a laser is a non-contact tool it offers several advantages, such asmechanical solutions or generally enabling new applications and implementation of new ideas that no one ever thought of.f The two essential beneficial factors are the speed o f t a directed light t blunt.

For the converting indu try, s y, several applications are currently in use and are

permanently being developed, and adaption to themarket requires newmaterials.

A classical application is the laser perforation on flexiblematerials for applications likemodified atmosphere packaging, where a deliberated gas exchange between the inner package and the outer environment is controlled by the hole sizes and amount per package. Also, aeration by little holes for frozen food packaging is common for a faster and tighter packaging.MLT offers solutions for a wide range ofmaterial widths andmaterial sorts, with several software functions to control all necessary processing parameters.MLT’s developed connection cards are the final backbone of the system; they connect the

Tomake this perforation package complete,MLT developed an image processing systemthat is capable of controlling and documenting the perfoforation process. For several customer groups a realised and automatically well-documented quality control ismore often favoured. The camera systemis well synchronised with the winding speed and captures the holes even at higher running speeds. TheMLT

Another application is the scribing process where the laser weakens thematerial in a well- defined depth, either just straight inmachin e direction or in various contours.

scribing depth can be easily defined byMLT software and laser settings, and finally varies fromcutting through defined layers in composite films or only touch somemicrometres in single componentmaterials like OPP.


The laser cutting applications start where the scribing process goes 100 per cent through the material. It is used for applications like windows in papers, films and banknotes, often before printing. Also, cardboardmanufacturers will profit fromthe high flexibility of the cutting systems. When asked about developing versatile systems and solutions,MLT

laser systems, the software and the consulting in all project phases, and all service offers, need to be well balanced to offer future-proof investment. Based inMunich, Germa y,ny,MLT
