“BPA-free” means that a product does not contain Bisphenol A, a chemical compound commonly used in the manufacturing of certain plastics and resins. BPA was widely used to make polycarbonate plastics and epoxy coatings due to its strength, durability, and heat resistance.
However, scientific studies dating back to the 1990s raised serious concerns about BPA’s potential health effects. Research has linked BPA exposure to hormone disruption, developmental problems, and possible effects on the brain and reproductive system, particularly in infants and young children. These findings have led many governments—such as in the United States, European Union, Japan, and South Korea—to strictly regulate or even ban BPA in food contact materials.
For example:
- California Proposition 65 sets a strict Maximum Allowable Dose Level (MADL) for BPA at 3 µg/day via skin exposure.
- The EU restricts BPA migration in coatings to no more than 0.05 mg/kg, and completely prohibits its use in products that come in contact with infant food.
- In Japan, BPA migration in plastic materials must not exceed 2.5 μg/mL, and in South Korea, the standard is 0.6 mg/kg for food-contact items.
To comply with these safety standards, KingStar uses BPA-free materials like Tritan, PP, and other food-grade plastics in our drinkware. This ensures our products are not only safe for everyday use but also meet global regulations for quality and health.
