Micro Laser Technology GmbH (MLT), located in Kirchheim near Munich is well known in the industry as a qualified & competent manufacturer of tailor-made laser material processing systems for industrial applications and operations, such as perforation, scoring/scribing (defined material weakening), embossing and marking.
MLT Laser machines are already worldwide in operation, mainly in the Packaging Industry (Food, Beverage and Pharmaceutical products), Tobacco & Paper Converting Industry and Automotive Industry.
Through our mission "Laser Excellence", we aim to deepen our invaluable knowledge & experience in order to design and manufacture cutting - edge laser processing systems.
Depending on material specification & perforation pattern, either Optical Multiplexing Technology or Scanner Technology will be implemented for micro- or macro laser applications, such as MAP (modified atmosphere packaging).
Micro- perforated films offer the possibility to tailor the OTR (Oxygen Transfer Rate) to suit the product being packaged. The aim is the customized permeability of the controlled gas exchange of CO2 and O2 for flexible bags or lidding films to enhance product shelf life.
The aim of macro laser perforation is to create ideal ventilation for vegetable packaging, fast exhausting during the filling process of bags, or to regulate the flow behaviour of highly viscous liquids in nearly all established packaging materials.
MLT offers laser scoring systems enabling the selective weakening of mono- and multilayer films during the converting process (offline) and on packaging machines (online).
For example, an easy opening feature can be created by processing materials in machine direction (MD), cross direction (CD) or in all variations of free-form contour scoring. The high precision level of adjustment possible ensures that material barrier properties are not negatively affected by the scoring process.
Many examples of easy opening, shaping and embossing solutions can be found in numerous areas of the food / non-food industry. The most recent introductions of such solutions include tear strip replacement, microwave openings or very customer-specific applications, such as embossing for brand awareness purposes.
Our modular base frame design for offline laser scoring systems enables a combined system structure containing all three scribing forms, which can also be retrofitted and up-graded at a later date to meet changing production demands.
Compact online laser scoring modules, which are integrated into filling and packaging machines, are designed and manufactured according to individual customer-specific requirements. These online modules ensure tolerance compensation during the packaging process, guarantee the fastest response time to any product or format changes and also allow for independent film supplier selection. MLT`s specially developed software allows "On-the-Fly" processing (set-point tracing) of the laser beam to ensure consistency during the winding ramp-up phase for cross direction or free form scoring.
Whether automotive, medical or pharmaceutical industry - the field of application in laser processing is continually expanding. Areas where laser perforation is applied includes: insulating tapes and wooden interior panels for the automotive industry, membrane film for fuel cells and tablets in the medical industry.
Laser material processing (selective weakening) is also becoming more common for airbag films, drinks packaging paperboard and tray packaging for consumer goods.
The labeling, embossing and safety coding of anti-counterfeit film for car license plates, traffic signs and holographic labels for original car spare parts or high quality cosmetics are yet just a few more examples illustrating the broad range of laser processing applications on the market today.
Turn-key marking laser systems from Micro Laser Tech fulfill the most stringent and significant quality standards. Film materials which can be treated include PP, PET, PE, PA, aluminum, and combinations thereof, as well as materials with a smooth surface.
These marking systems can be equipped with various laser sources to superimpose barcodes, company logos, security features or number combinations on a wide variety of materials, such as metal, paper or plastic. Our marking systems generate exact and high-precision markings during all machine sequencing such as "on-the-fly" or interval cycle.
