PETG products containing recycled material hygienic performance risk
Problem Phenomenon
Food contact products containing recycled material have a risk of exceeding the standard in migration testing.
Cause Analysis
The recycled material may contain restricted substances (BPA, heavy metals, etc.), and multiple thermal histories produce new migrants.
Solution
Do not use recycled material for food contact products, or only use closed-loop clean waste; establish a traceability system.
Key Takeaway
PETG food contact applications have strict requirements for recycled material management.
