- Virgin pulp type, and
- Recycled pulp type.
In addition, paper for food contact is classified into 2 types based on the application;
- Sheet paper for processing, and
- Container type (molded / sheet-processed).
Requirements for materials

In the case of recycled pulp type, it must not be made from or contain paper originated from contamination sources, including wastes, used sanitary paper, and carbon paper. Chemicals used in the production process, printing ink, and adhesive materials must be food contact grade.
