We’re afraid that the plastic bottlescome with air bubbles, black spots andwater ripples. How did you preventsuch defects?

What LYRA did:

Here are the main causes of air bubbles, black spots and water ripples: improper drying of PET bottles, uncontrolled heating and stretching speed of preforms, uncleaned machine interior, and non-virgin PET raw materials.

To avoid these issues and deliver qualified products, we follow standardized production SOP and conduct 100% full visual inspection under lights after production.
