Color migration of PLA colored products
Problem Phenomenon
The color of PLA colored products contaminates the contact objects.
Cause Analysis
The migration resistance of the dyes used is poor, and the degradation products of PLA itself carry color.
Solution
Select migration-resistant pigments (pigments approved for food contact); control the processing and storage temperature.
Key Takeaway
PLA color migration is a key concern for food packaging.
