CO2 laser coder application case: date code onto transparent plastic bag

 When it comes to marking date codes such as date of production or date of expiry onto plastic bags (PET for example), CO2 laser coders are the ideal choice for businesses due to the following reasons:

1. It is a non-contact marking process, eliminating the risk of damaging or deforming the plastic bag during the marking process. 

2. CO2 laser markers produce clear and permanent marks, ensuring readability and traceability.

3. The marks by CO2 laser marking machines are permanent, resistant to wear and tear. This makes sure the mark remain intact throughout the products' lifecyle.

4. Automation integration: CO2 laser marking machines can be integrated into automated production lines. It can be used together with conveyor belts or robotic arms, to achieve high-speed marking of products within a short period of time.

   For the coding of opaque plastics, UV or fiber laser markers are to be applied. We always recommend that our customers send their products for sample marking, so as to find the most suitable laser type and laser wattage for their specific needs.
