Why Use A CO2 Laser Marking Machine For Plastic?
Plastic marking is not simply about putting a logo on a surface. Manufacturers may need to identify every part, add a production code, create a permanent serial number or mark packaging without adding labels or ink. A CO2 laser can be a practical choice when the plastic absorbs the laser wavelength well and the required marking effect is compatible with thermal processing.
Permanent Identification
Create durable product information directly on suitable plastic surfaces without applying labels.
Clear Product Branding
Mark logos, names, symbols and product information for industrial and consumer products.
No Ink Or Labels
Laser marking is a direct, non-contact process, which can reduce dependence on printing consumables.
Easy Digital Changes
Change text, serial numbers, logos or production codes through marking software without making physical plates.
What Plastics Can A CO2 Laser Mark?
CO2 laser marking works well on many plastic materials, but there is no single laser setting that works for every plastic product. The polymer itself, color, additives, fillers, surface coating and required marking appearance can all change the result.
For this reason, we recommend testing your actual plastic parts before choosing a production configuration. A sample test can help determine the appropriate laser power, speed, frequency and marking method.
| Plastic Material | Typical Applications | CO2 Laser Consideration |
|---|---|---|
| Acrylic / PMMA | Signs, displays, decorative products | Generally well suited for CO2 engraving |
| PET | Bottles, containers, packaging | Can be suitable depending on formulation and required contrast |
| PE / HDPE | Containers, industrial products, packaging | Test marking parameters and material formulation |
| PP | Caps, containers, automotive parts | Results depend strongly on additives, color and surface composition |
| ABS | Electronic housings, industrial components | Can be marked, but UV may be preferable for some high-contrast applications |
| PC / Polycarbonate | Electronic and industrial components | Requires application testing to control heat effects and contrast |
For sensitive plastics or applications where heat must be minimized, compare this solution with our UV Laser Marking Machine For Plastic .
CO2 vs UV Laser For Plastic: Which One Should You Choose?
Both CO2 and UV lasers can be used for plastic marking, but they work in different ways. CO2 lasers use a much longer wavelength and rely more heavily on thermal interaction with the material, while UV lasers can produce marking through a photochemical process with much lower heat input.
| Consideration | CO2 Laser | UV Laser |
|---|---|---|
| Typical Wavelength | 10.6 μm | 355 nm |
| Marking Mechanism | Primarily thermal material removal | Primarily photochemical interaction |
| Acrylic | Excellent candidate | Can also mark |
| Heat-Sensitive Plastic | Requires careful parameter testing | Often the better option |
| Deep Engraving | Strong candidate | Usually selected for precision marking rather than thermal engraving |
| Packaging | Very useful for suitable films, containers and packaging | Useful where low heat and fine detail are priorities |

Can A CO2 Laser Engrave Plastic?
Yes, a CO2 laser can engrave certain plastic materials by removing material from the surface. However, the achievable engraving depth and appearance depend heavily on the plastic type, thickness, color, additives and laser parameters.
For simple product identification, a shallow marking may be enough. For decorative products or applications that require visible material removal, multiple laser passes can be used to increase the engraving effect when the material allows it.
Shallow Marking
Suitable for logos, product numbers and other identification information.
Surface Engraving
Creates a more visible engraved appearance by removing material from the surface.
Multi-Pass Engraving
Multiple passes may be used when a deeper result is required and the material can tolerate the additional heat.
