- Household wrap (Saran Wrap, etc.)
Found in food, water and the human body
- No study measuring polyvinylidene chloride in foods or the human body was found. It is not among the targets measured in the main human-body studies
Evaluations of raw materials and additives
- The raw material vinylidene chloride is IARC Group 2B (evaluated in 2017)
IARC classifications rate the strength of evidence that something can cause cancer, not the size of the risk at everyday amounts.
Japan's standards (utensils, containers and packaging that touch food)
- MHLW Notification No. 370 (polyvinylidene chloride): vinylidene chloride in the material 6 μg/g or less, barium 100 μg/g or less
General standards for all synthetic resins: cadmium and lead in the material 100 μg/g or less each, heavy metals migrating (as lead) 1 μg/mL or less, and others. Since June 2020, synthetic resins that touch food have been under a “positive list system” that sets which substances may be used (the transition period ended May 31, 2025). → Rules and regulation
