» High-Speed Flexible Packaging Modules Tailored to Your Needs

Are you looking to enhance production speed, flexibility, and efficiency with customer-oriented solutions? Challenge us! We pride ourselves on being a world leader in providing unparalleled solutions.

With our state-of-the-art equipment, you can achieve perforation speeds of up to several

hundred meters per minute and more than 1,000,000 holes per second on some materials. We aim to accelerate your processes rather than being a bottleneck.

Our machinery, designed to process efficiently, exceeds the capabilities of most competitors. We are devoted to serving you with machines specifically designed to match your processes and standards.

Laser perforation has many advantages over other processes, e.g:

  • Contactless, i.e. free from mechanical wear
  • Realization of high speed
  • High accuracy and smallest microperforations (or smallest hole sizes)
  • No tool changes are required to set hole sizes and shapes

 

» Applications for Laser Perforation Technology

Laser perforation is an optimal alternative to traditional methods due to its precision, high speed, and the elimination of tool costs and changeover times. Explore the applications below where our machines are contributing to success:

» What materials can be processed on a laser perforation machine?

Laser perforation can be implemented on a variety of materials. Particularly common are materials such as mono- and composite films (OPP, PE, PE-LD, PET, PP, CPP, EVA, PLA), paper, and kraft paper. Since uniquely high speeds can be achieved, this technology is especially attractive for web and roll materials, which are often processed very quickly.

FAQ Laser Perforation Machines

What are the advantages of a laser perforation system over traditional tool-based machines?

Laser perforation offers numerous advantages over other methods. For example, the perforation, meaning hole size and shape, can easily be adjusted through software parameter changes. Hole position, hole diameter, and the distances from hole-to-hole are maintained precisely and with repeatability. A tool change or even a new tool (e.g. perforation roller) is not required for this. In the food sector, the contactless processing by the laser machine can also be an advantage. Thanks to specially developed beam guides and special laser sources, MLT laser machines achieve absolute precision even at the highest speeds. Are you unsure whether laser perforation is applicable for your use? Ask us - we will advise you without obligation!

How big or small are the holes that can be created by laser microperforation?

For most applications, hole diameters in the range of 40µm to 800µm are produced. There are also many possibilities outside this range. We will check the feasibility of your application at any time without obligation! Just contact us to discuss your requirements!

What speeds can MLT machines achieve during the laser perforation?

MLT machines can achieve highest speeds in microperforation! Perforation speeds of up to 800 m/min and hole counts of more than 1,000,000 holes per second can sometimes be achieved on film or paper webs. We would be happy to check the possibilities for your application in detail.

What laser sources and laser powers are used in MLT laser perforation machines?

Often  CO2 laser sources are used in combination with specially developed beam guides and we usually use fiber lasers for metal foils and applications within the battery industry for examlpe.. The power of the laser sources is typically between 30 watts to 4000 watts per source - whereby we very often have many lasers in use simultaneously in one system.
