Laser technologies at a glance
Laser marking systems offer diverse solutions for a wide range of materials and applications. From metals and plastics to flexible packaging - each laser technology has its specific strengths and areas of application. We present the three main technologies below: Fiber lasers, CO2 lasers and UV lasers.
Fiber laser
How does a fiber laser work?
A fiber laser generates its beam in a glass fiber core and guides it to the processing location via light guides. This technology is energy-efficient and ideal for precise markings on hard materials such as metals.
Areas of application and advantages
Particularly suitable for the laser marking of aluminum and tinplate cans in the food and beverage industry, e.g. for best-before dates or batch numbers.
- Durable markings: Resistant to heavy use.
- High precision: Easy-to-read codes on small surfaces.
- Efficient: Reliable at high production speeds.
CO2 laser
How does a CO2 laser work?
CO2 lasers work with infrared radiation (10,600 nm), which specifically triggers thermal reactions on the surface of a material. The effect of the heat leads to permanent marking through vaporization, foaming or discoloration. This technology is particularly suitable for organic materials and offers reliable results at high production speeds.
Areas of application and advantages
CO2 lasers are particularly suitable for packaging materials such as cardboard, paper, glass and plastics. Thanks to their efficiency, precision and versatility, they are an established solution in numerous industries.
- Variety of materials: Suitable for paper, cardboard, PET, glass, wood and many plastics.
- High precision: Clear markings even with small codes and high speeds.
- Cost-effectiveness: No consumables, low maintenance.
- Sustainability: Environmentally friendly thanks to emission-free, contactless marking.
UV laser
How does a UV laser work?
UV lasers work with ultraviolet wavelengths (355 nm), which trigger a photochemical reaction in the uppermost material layer. In contrast to other laser types, the UV laser does not remove any material, but changes the surface gently and without thermal stress.
Areas of application and advantages
UV lasers are particularly suitable for sustainable packaging materials such as monofilms, colored and white plastics and medical products. They deliver precise, high-contrast results without damaging the material.
- Material protection: Reliable marking without eroding or impairing the barrier properties.
- Highest precision: Perfect for filigree codes with a beam diameter of 30 µm.
- Versatility: Suitable for packaging made of PE, PP and flexible films.
