1. Introduction to Japanese Food Contact Grade Testing:
Food grade testing in Japan is regulated by the Japanese Ministry of Health, Labour and Welfare (MHLW), under the relevant legislation, the Japan Food Sanitation Law (Law No. 370).
The Food Sanitation Law prohibits the production, sale, or use of food contact materials and articles that may contain substances harmful to human health. The MHLW can establish corresponding standards as needed. Standards are divided into three categories: general standards, category standards, and specific-use standards. General standards specify requirements for heavy metals, particularly lead, in food contact materials and articles. Category standards have been established for 13 types of polymers, including metal cans, glass, ceramics, and rubber. Specific-use standards regulate materials for particular applications, such as packaging for pasteurized milk and street food packaging.
2. Materials Covered by Japanese Food Contact Grade Testing:
Paper, glass, ceramics, enamel, rubber, metal, plastics, organic coatings, silicone, wood.
