LANG LASER-System GmbH

Product 1: EasyLine, ContourLine and CombiLine
Laser systems for scoring/scribing, perforating and cutting (window-cutting)


EasyLine WD

• From the manual basic system to the fully automatic PREMIUM laser-system

EasyLine WD gives you technology that can make the finest scribing lines at high speed in the material. The process runs in the web direction. The scribing is done with individual laser beam sources and precision optics. Each beam, with its own focusing optics, produces a scribing or perforation pattern. The high precision MFO module (Multi-Focus Optics) splits, if necessary, each laser beam into two or more beams, to get more spots in parallel. This produces parallel precisely-running scribing structures, with spacing that is adjustable. Double or multiple tear lines are used to compensate the tolerances on the pouch making machines. This scribing lines can synchronized with the film print if necessary.

Your advantages:

• Finest, almost invisible scribing lines
• Unique performance with 16 focusing heads in two or more levels
• Up to 80 scribing or perforation patterns with Multi-Focus Optics
• Scribing and perforating processes in a single production step
• Combination of different hole sizes and scribing line lengths
• Fast product/job change
• Consistently high quality
• Powerful and easy-to-use control software

ContourLine CW-Free Form

• From the manual basic system to the fully automatic PREMIUM system

Scribing is also often done in the Cross-Web direction or free form contours, it is named “Cross Web” or CW for short. ContourLine is extremely dynamic and precise, for scribing it removes only single layers without damaging the barrier properties. The print mark control synchronizes different scribing structures and thus allows numerous applications: from simple lines to complex contours for re-closable packaging. This means that even diagonal and semicircular openings of the highest precision can be made.

High-Tech 2-axis (2D) or 3-axis (3D) scanners ensure the necessary beam deflection. They are up to every challenge and master:

• Finest focus diameter
• Highest available deflection speed
• High contour freedom
• Perfect compensation of the web speed
• Various working areas (2-axis scanner head / 3-axis scanner head)
• Special quality characteristics

Depending on the application, the ContourLine can be easily integrated into existing systems;

• Slitters and rewinders => Scribing, Perforation and Cutting
• Print Presses => Perforating PE or PET film for a customer friednly

tear for outer packaging

• Laminators => Cutting paper before the laminating process, named

Window- Cutting, combined with a special suction/filter
system for safe suction for sticky cut-outs

CombiLine

The CombiLine is a very flexible laser system in which perfect scribing lines or perforations can be realized in the web direction or cross web direction as well as free-shape contours.

The CombiLine allows you to scribe and perforate in one process. You vary any hole pattern and scribing lengths or contours and synchronize this process with the print image of your packaging. The optimum solution for complex production processes.

The interplay of different methods is achieved by our 2-axis scanner system with different lenses, or 3-axis scanner system with switching to focusing heads. CombiLine offers a system with almost unlimited possibilities.

Your Advantages:

• Finest, almost invisible scribing lines

• Easy to use of the Multi-Focus Optics (MFO)
• Unlimited contour freedom
• Highest application flexiblility
• Best suitability for complex processes
• Easy change from WD to CW or free form applications
• Powerful and easy-to-use control software

Product 2: PouchLine

• for easy integration into all common pouch-making machines for scribing identical lines or contours

Pouch packaging can only be easily opened if the scribing lines or contours on both sides are in line. This is achieved when the laser on the pouch-making machine simultaneously makes the lines on the front and rear side after folding the flat foil.

The PouchLine has been successfully integrated into all common machine types.

Your advantages:

• Exact lines through high-quality laser processing
• Easy opening is made possible by coincident scribing lines or contours on both sides of the bags
• Compact design
• Easy Integration
• Low Investment

Product 3: PerfoLine

• From micro-perforation for MAP applications in the freshness sector to full-surface perforation with over 1,000,000 holes/ second

Fine perforations with the laser ensure that your packaging breathes. A controlled oxygen exchange ensures that the contents remain fresh and durable for longer. The method is called Modified Atmosphere Packaging (MAP). Microscopic, precise holes of 60µm – 100µm in diameter ensure an optimal climate.
The micro-perforation even controls the exchange of certain gases that, for example, accelerate the ripening process of cheese.


With the Web Speed Compensation WSC technology developed by us, you can perforate foils with holes in a consistent round shape at web speeds of up to 600 m/min. Our technology allows constant quality even when the speed changes during the acceleration.

PerfoControl – Inline process control

Process control is becoming increasingly important, which has led to the development of the PerfoControl module at LANG LASER. With this system, every hole from a diameter of 50 microns up to 300 microns or more is detected even at web speeds of up to 300m/min and measured in its diameter. The values are then visualized via a diagram. For quality control, limit-values for the inline process can be specified.


For perforation all over the web, we offer system solutions from the narrow web up to 2 meter wide material webs, with individual arrangement of the holes. During perforation, the hole diameter or the hole depth (sack holes) can be freely selected. Depending on the hole matrix, very high web speeds can be achieved with a perforation performance of 1,000,000 holes/second.

Perforation of the finest technology:

• Micro-perforation for MAP
• Inline process control (100% control – circular area calculation)
• Consistent hole quality thanks to Web Speed Compensation WSC technology
• Extremly high perforation performance > 1.000.000 holes / second
• Freely selectable arrangement and diameter of the holes
• Constant hole diameter even in case of speed changes
• Web widths up to 2 meters
• Use for a wide range of materials or material combinations

Product 4: SecurityLine

• From personalizing of international passports and perforating security features in banknotes to marking foil or paper webs, LANG LASER offer always the best solution.

LANG LASER offers turnkey systems for small series production up to mass production when marking flexible web materials. The safety features and markings meet the highest quality standards.

The use of laser beam sources with different wavelengths and pulse properties (CO₂ lasers, fiber lasers, diode lasers ...) enable the placement of summate numbers, markings, security codes on flat materials, such as metal foils, plastic films, paper or cardboard.

Depending on the machine cycle time or speed, high-precision markings are on the fly processing "On The Fly - OTF" are also placed in the moving web at web speeds up to 300 m/min.

Product 5: PaperLine

• From quantity 1 to mass production, LANG LASER supplies highly innovative laser technology for the production and finishing of folding cartons.

With fast mirror deflection systems, the laser beam will be focused to the cardboard web or sheet of cardboard at extremely high speed for cutting, creasing and engraving. The lines, contours and filigree cutting or engraving designs are created via a graphics program specially developed for these processes.


Thanks to the laser technology developed by LANG LASER, the production of folding cartons is completely digital and enables fast product changes, short turnaround times and high flexibility. In addition to the folding and cutting contours, very decorative cut-outs or engravings can also be inserted at the same working run.


Your Advantages:

• No use of punching tools
• No tooling cost
• Low production costs with highest availability
• High flexibility and short delivery times (Just in Time)
• From quantity 1 to mass production
