What is Laser Scoring?
Laser scoring is a non-contact manufacturing process that creates precisely engineered tear lines for reliable, controlled opening. A focused laser beam is used to selectively melt, remove, or structurally weaken the material. Unlike laser cutting, the material is not cut all the way through. Instead, it is processed to a precisely controlled depth.
The result is a reliable tear line that opens exactly where intended without mechanical tools, tool wear, or compromising repeatability.
Laser scoring is particularly valuable for applications where mechanical processing is too inaccurate, inflexible, or maintenance intensive.

Frequently Asked Questions (FAQ)
What is the difference between laser scoring and laser cutting?
Laser scoring processes the material only to a defined depth without cutting completely through it. The objective is to create a controlled tear line rather than a complete cut.
How deep can laser scoring be performed?
The scoring depth depends on the material and can be controlled with exceptional precision, ranging from just a few microns to almost the full material thickness.
Is laser scoring suitable for high speed production?
Yes. Laser scoring is ideally suited for inline applications with continuous web materials and high production speeds.
Can laser scoring be combined with other laser processes?
Yes. Laser scoring can easily be combined with laser perforation, laser cutting, or laser marking within a single production system.
Does MLT develop customized laser scoring solutions?
Yes. MLT designs and builds custom laser systems that are tailored to your specific production requirements.
