Hot soy milk, ice drinks, fresh milk... These delicious drinks are inseparable from the "company" of straws. When drinking canned drinks, many people are accustomed to being accustomed to drinking habits, thinking that it is not convenient and healthy to drink drinks directly from the mouth, but this is not the case. Using some bad drinking straws will harm your health! As everyone knows, a small straw can damage the liver, kidneys or even cause cancer. 
The main component of plastic straws is generally polypropylene, which is relatively stable at 70 to 80 degrees Celsius, but may produce harmful substances at high temperatures. Regular plastic pipettes have a maximum temperature limit, and three non-suction pipes may be processed from recycled waste plastics, which is even more harmful to the human body.
Garbage suction hazards 1. Raw material may be waste plastic. Dong Jinshi, general secretary of the International Food Packaging Association, said that the raw materials for straws are generally high-density polyethylene, and the polyethylene raw materials are classified into food grade and non-food grade, and the food grade is 1000-2000 yuan/ton more expensive than the non-food grade. The difference in the cost of drinking straws made from different materials is very obvious. The raw material for the production of "three-nothing" plastic straws may be industrial-grade polyethylene or even waste plastics.
2. Use pigments to cover quality problems. Dong Jinshi emphasized that some unscrupulous merchants will stain straws in order to cover up the variegated straws made of waste plastics. The brighter the colors, the greater the potential safety risks. “The quality of plastic straws that are too bright in color is definitely a problem. Once you use it to drink juice or hot drinks, harmful substances will be released, which will cause harm to the human body.†Dong Jinshi said.
3. Dispels heat and emits toxic substances. "If the straw encounters a hot drink and emits a plastic smell, it certainly belongs to the problem straw, because the normal PP, can withstand high temperatures above 100 °C, will not emit plastic flavor when exposed to heat." China Plastics Processing Industry Association professional degradable plastics Deputy Chairman Tang Saichen emphasized that some unscrupulous merchants often use waste plastics for recycling in order to reduce costs and maximize profits, and it is difficult to ensure a safe and hygienic production environment. Inevitably, some pathogenic bacteria will be contaminated. When such a straw is used, toxic and harmful substances in the plastic will dissolve in the water, and long-term use will cause harm to the human body's liver and nervous system, especially after high-temperature burn, the harm to the human body is even greater.
