Tritan, known as copolyester in Chinese, is a new food contact material. As far as the current research is concerned, the purchase of national production standards, in accordance with the product instructions, the use of tritan in the use of temperature range, there is no harm. Because of high transparency, good toughness, impact resistance, not easy with strong acid and alkali chemical reaction, and does not contain harmful bisphenol A and any other bisphenol substances, has become the Europe and the United States designated material for baby products. Traditional plastics, such as PP, contain high levels of BPA and other bisphenol residues. BPA is a fat-soluble substance that easily enters the body with the diet, and long-term exposure affects the human endocrine system, immune system, nervous system, etc., and seriously interferes with human reproductive genetic function. Therefore, current research shows that purchasing Tritan products that meet production standards and using them in accordance with the product’s instruction manual will not be harmful to the human body.
