Because most plastic bottle in the case of high temperature chemical molecule is not stable, it will release harmful substances to human body. As bisphenol A and phthalates, the two substances have the potential risk to the human body, bisphenol A cancer-causing, may disrupt the endocrine system, can also lead to reproductive function decline, and phthalic acid may cause male endocrine disorder.
However, not all plastic bottles are unstable or harmful, there are also some heat and corrosion resistant plastic materials.
