Can ceramic fibers be used in food packaging materials?

Ceramic fibers are not typically used in food packaging materials due to concerns over their safety and potential health risks. They are known for their heat resistance and strength, which makes them suitable for industrial applications such as insulation and construction. However, for food packaging, materials must meet strict safety standards to ensure they do not leach harmful substances into food. Traditional food packaging materials include plastics, paper, and metals, which are regulated for food contact safety. Ceramic fibers, without specific food-grade certification and due to their inorganic nature, are not considered safe for direct contact with food.
