Scope of application

Our MLPerf laser system is mainly used by two customer groups: Film manufacturers or film converters and directly by customers from the food industry who use our laser systems on packaging machines.

Fresh foods such as fruit and vegetables often have a long journey before reaching the customer. In the packaging industry for example the following methods and products are used:

  • Modified Atmosphere Packaging (MAP),
  • Easy Ventilation or
  • Breathable Film

A constant equilibrium in the gas exchange of CO2 and O2 with the environment is created in the packaging through the relatively small holes that are created. In principle, the packaging begins to "breathe" in the refrigerated counter. Ripening gases can escape in a controlled manner and, as a result, the packaged food usually has a much longer shelf life.

The main areas of application for the MLPerf laser perforation systems are:Laser perforation of monofilms

  • Laser perforation of monofilms
  • Laser perforation of laminated films
  • Laser perforation of outer packaging during the packaging process.
  • Special applications in the pharmaceutical and automotive industries for ventilated packaging solutions

The technology

  • Typical materials: Mono and composite films (OPP, PE, PE-LD, PET, CPP, EVA, PLA), paper and cardboard.
  • Typical integration: In slitter rewinders, winders.
  • Speeds: Typical industrial speeds range from 80m/min up to 400m/min. In special applications over 700m/min are realised.
  • Type of laser source: CO2 laser.
  • Typical hole sizes: 80µm to 900µm - depending on the material, both smaller and larger holes are possible.
  • Number of laser sources per system: 1 to 18 - usually between 4 to 10.
  • Power of the laser sources: 30 Watt to 1000 Watt per source - usually between 60 and 120 Watt per laser.
  • Web widths: 250mm to 2000mm (larger web widths are usually possible).

Your advantages

  • High-quality laser perforation is the main area of application - but flexible scoring, cutting of paper types, cardboard, mono films or laminated films can also be optionally combined.
  • We offer system solutions for all typical widths of film material on the market.
  • Our MLT systems can be individually adapted to your existing machines.
  • Optimal design of the laser components to the specific requirements of the respective industries and use of MLT patented technologies.
  • MLT develops overall concepts and solutions: From application development to turnkey installation, everything comes from a single source.
