Food grade inks refer to special inks that, once dried, can safely come into contact with food without contaminating it. Although these inks are not edible, they comply with strict food safety standards and regulations to ensure they do not pose any risk to food products in applications like packaging and labeling.

Characteristics of Food Grade Inks

1. Non-toxic: Food grade inks are free from harmful chemicals and toxins, ensuring they do not contaminate food upon contact.
2. High Safety: These inks undergo rigorous testing to ensure their safety once dried and in contact with food.
3. Regulatory Compliance: They meet international food safety standards, such as those set by the FDA in the United States and the EU regulations.
4. Temperature Resistant: They maintain stability under various food processing and storage conditions, without decomposing or releasing harmful substances.
5. Odorless and Tasteless: They ensure that the ink does not affect the taste or smell of the food.
