Application Example Reliable Laser Marking of COC and COP

COP (cyclo-olefin polymer) and COC (cyclo-olefin copolymer) are among the most innovative plastics. Their exceptional properties, such as high transparency and break resistance, make them ideal for applications in medical technology, for example in pre-fillable syringes. However, these highly transparent plastics place special demands on marking. The marking must be permanently legible, high-contrast, and secure without damaging the material.

The application note “Gentle laser marking of COC/COP” shows how these requirements can be met with a precise, additive-free process—highly efficient thanks to an automated, camera- and software-based process.

Dive into the details:

• What are the challenges when marking COC and COP?
• Which technology meets the requirements – without compromise?
• How can these demanding polymers be marked reliably without additives and without thermal stress?
• What effect does “cold laser marking” have on transparent plastics?
• How does the continuously adjustable pulse width support precise marking?
• How does an automated, software-controlled process ensure maximum efficiency and safety?
