ML Scribe

Product Details

Laser scribing is mainly used for scribing materials in a precisely defined area. The aim is to produce packaging that is easy to open for the consumer. The laser weakens the packaging materials through a defined laser line with great precision and repeatability.

Application

  • Laser scoring of mono and laminated films:
    Stick packaging for instant coffee; pouch packaging such as sachet soups;
  • Opening aids for hygiene articles; packaging for pet food.
  • Laser scoring of cardboard packaging.
  • High-quality folding boxes and similar packaging benefit from this technology.
  • Processing of recyclable mono materials such as PE, PE/PE laminates, PET and others.
  • Special applications in the pharmaceutical and automotive industries for the creation of precise folding geometries or tear-off aids for example opening valves & pre-determined breaking points.

Different methods of laser scribing are used for different applications:

  • Laser scribing in the running direction of the web material
  • Laser scribing transverse to the running direction
  • Laser scribing in freely definable geometries
  • Using Dual-Spot or Trippel-Spot optics, several scribing lines can be generated simultaneously in machine direction.

Product Features

  • High-quality laser scribing for "easy opening" is the main area of application - but flexible scribing of cardboard or other materials can also be realised.
  • MLT systems can be individually adapted to your existing machines.
  • Very precise and stable scoring results.
  • MLT offer system solutions for all typical widths of film material in the market.
  • MLT develops overall concepts and solutions: From application development to turnkey installation.

Comparison

  • Typical materials:
    Mono, and composite films (OPP, PE, PE-LD, PET, CPP, EVA, PLA), cardboard, nonwoven materials, fabrics.
  • Power of the laser sources:
    • 30 Watt to 600 Watt per source - usually between 30 and 200 Watt per laser.
    • Variable DualSpot optics for scribing double lines - with patented MLT technology.
    • TrippleSpot optics for scribing triple lines.
  • Speeds in WD:
    Typical industrial speeds are between 200m/min up to 500m/min. In special applications over 700m/min are realised.
  • Number of laser sources per system:
    1 to 12 - usually between 2 and 6.
  • Typical integration:
    In slitter rewinders, winders
  • Speeds in CD:
    Typical industrial speeds here are between 80m/min up to 450m/min and more.
  • Type of laser source:
    CO2 lasers of various power levels.
  • Web widths:
    250mm to 2000mm (larger web widths are usually possible).
