LO Series - LaserScan 2D/3D
Laser Perforation Model LaserScan 2D/3D
From straight lines to any shape you can draw
Spark Machinery laser systems are engineered to microperforate continuously moving films with high-precision CO₂ laser sources. The same technology can also cut, pre-cut and score the film. Scoring weakens the material in a controlled way without perforating it, which is how easy-opening solutions are made.
With precise microperforations, laser technology is widely used in Modified Atmosphere Packaging (MAP). The holes regulate airflow and gas exchange through the film, extending shelf life and preserving product quality.
A scanning laser, not only machine direction
LaserOne Line and LaserOne Track perforate continuous lines in machine direction. LaserOne Scan goes further: galvanometric mirrors move the beam freely inside a working field, so the laser can work across the web and draw whatever the recipe describes. Cross-web perforation lines, holes arranged in circles or grids, custom drawings and cross pre-cuts for easy opening all come from the same machine.
LaserOne Scan is one model in two configurations. The 2D version uses two galvo axes and is the choice for precision and speed. The 3D version adds a third axis that drives the focus, so it can cover much larger areas.
Functioning of LaserScan 2D/3D model
How it works
The CO₂ laser source emits light pulses at a predetermined frequency. A beam expander collimates and widens the beam, two galvo mirrors steer it along the X and Y axes, and a focusing lens concentrates it onto a small, precisely defined area of the moving film. In the 3D version, a motorised Z axis moves the focus as the beam travels across the field. The energy of the beam sublimates the material, opening a clean microperforation with no contact and no tool wear.
Integration
LaserOne Scan is designed as a unit to be integrated into film converting lines such as slitter-rewinders, extruders, printing machines and rewinders.

† On the 3D configuration, the maximum speed depends on the focus travel the requested job needs: the more the beam has to refocus across the field, the lower the speed.
Key features
2-axis galvo scanner (2D)
Two galvanometric mirrors steer the beam along X and Y inside fields from 50 × 50 to 300 × 300 mm. Compact fields keep the spot small: holes from 60 µm on 50 × 50 mm and from 100 µm on larger fields, at speeds of up to 400 m/min.
3-axis galvo scanner (3D)
A third, motorised axis moves the focus while the beam travels, so the spot stays focused across working areas up to 1,800 × 1,800 mm. Combined with machine vision, focusing is fully automatic.
Automation
Patterns, hole sizes and laser parameters are stored in recipes, so a new job starts in minutes. The software controls every head independently and corrects the holes automatically.
Camera-based quality control (optional)
A vision system inspects the holes in real time, measuring free area, deviation from the theoretical diameter and the melting ring. When it finds a deviation, it adjusts laser power and pulse duration, and on 3D also the focus, without stopping production. A quality report is saved for each reel.
Industry 4.0 and remote support
Built for Industry 4.0, the machine is managed from a touch-screen panel where your operators store every perforation parameter as a recipe, and it connects to your factory systems to exchange production data with your MES or ERP. Through remote assistance our technicians check parameters, diagnose faults and update the software without waiting for a site visit, and support your team live during commissioning or when a new recipe is set up.
Made for modified atmosphere packaging
Fresh produce keeps breathing after harvest. Micro-perforation lets packaging exchange a controlled amount of oxygen and carbon dioxide, so the atmosphere inside stays balanced and shelf life gets longer.
