1. Migration test: This method is used to determine the migration of substances from paper, paperboard, and paper products into food. It involves simulating the conditions under which the food contact material would normally be used and testing the migration levels of specific substances.

2. Overall migration test: This test determines the overall migration of substances from paper and paperboard into food simulants. It provides an indication of the total amount of substances that can migrate from the material.

3. Specific migration test: This method is used to determine the migration of specific substances, such as heavy metals, from paper and paperboard into food simulants. It focuses on the migration of individual substances of concern.

4. Chromium migration test: Chromium is a common component of inks and pigments used in printing on paper. This test evaluates the migration of chromium from paper and paperboard into food simulants.

5. Acidity test: This test assesses the acidity of paper and paperboard to ensure that it does not impart any acidic substances to food, which could affect the safety and quality of the food product.

6. Moisture resistance test: This test evaluates the resistance of paper and paperboard to moisture, ensuring that the material does not easily absorb or transfer moisture to the food product.
