Can plastic be laser marked?

Some lasers are capable of marking plastic. The right laser for you will depend on the type of plastic you are marking and whether or not you are marking other materials in addition to plastic. For example, a CO2 laser is great for marking a variety of different plastics. However, if you also want to mark metal, an infrared or green fiber laser could be a better option, depending on the type of plastic you are marking.

Understanding your needs and the capabilities of laser sources is important when choosing your laser. This is especially true when laser marking plastic as there are more variables to consider than when laser marking metal. However, we can help you make sense of your options and find the right laser for you. Give us a call at 800-323-1332 to discuss your applications and our laser options.

Marking Plastic

TYPES OF PLASTIC LASER MARKS

Lasers may produce different types of marks on plastics. Here are the most common types.

Laser Carbonization

Carbonization is a thermo-chemical laser marking process that produces high-contrast marks on synthetic polymers. Laser carbonization is typically performed on light and clear polymers and result in a dark or gray laser mark. 

Foaming

Laser Foaming, sometimes also referred to as frothing, occurs when the laser beam heats the surface of a plastic that contains carbon. The heat causes oxidized gas bubbles (i.e., foam) to form in the top layer, resulting in a raised mark.

Vaporization

Vaporization is essentially laser engraving plastic. The heat from the laser causes the plastic to melt, leaving a groove in the plastic after it cools.
