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).
