Recently, food safety problems have occurred frequently. Not long ago, the issue of “plasticizer foods†in Taiwan caused a great deal of uproar. Actually, not only plasticizers but also many kinds of health and safety hidden troubles around them: plastic bags containing foods were not qualified. Drink bottles used multiple times, uneven quality of disposable lunch boxes and so on. What are the respective harms? How should people identify and stay away from these hidden dangers? On July 5th, Dong Jinshi, a famous environmental chemistry expert, environmental protection expert and secretary general of the International Food Packaging Association, interpreted how to identify potential safety hazards in food packaging around him.
Plasticizers What plasticizers are mainly used in plastics, there are about 100 kinds, and there are 20 kinds of plasticizers used in food packaging.

Not all plastic products contain plasticizers, mainly because PVC is harder and softer. In addition to plastic products, perfumes, lipsticks and nail polishes contain plasticizers.
Plasticizers can pollute the environment. They are environmental hormones that can affect the endocrine through the environment and even the sex and physiological functions through the environment. They have serious carcinogenic effects.
If you inadvertently ingest plasticizers, the intake can be reduced by drinking water, drinking milk, and eating more fruits and vegetables. However, long-term intake is best to go to the hospital for treatment.

In addition, the catalyst metal hydrazine in the water bottle can be easily released and used to affect the liver, kidneys and nervous system.
Most plastic cups and cups on the market today are made of PC materials, especially cups are inevitably hot water. Although the temperature on the tea cup is marked at -30 to +137 degrees Celsius, there are traces of harmful substances such as bisphenol A. The preferred glass and ceramic cup for drinking water.
