In plastic cap production, the choice of color masterbatch is directly linked to product safety. At Mingda, all masterbatches used are food-grade, meeting both domestic and international safety regulations for food-contact materials.
Compared to regular masterbatches, food-grade masterbatches have several key advantages:
- Free of heavy metals and harmful additives
- Compliant with FDA and other global food-contact safety standards
- No release of toxic substances during high-temperature molding
- No impact on sealing performance or material stability
We maintain strict control over sourcing and usage of all colorants, and our materials undergo third-party testing (e.g., SGS, FDA certification) to ensure safety and compliance, especially for export markets.
Choosing certified manufacturers and food-grade masterbatch is essential to protecting consumer health and maintaining brand trust.
