Because of its changeable shape, bright color, low price, and not easy to break, plastic water cups are loved by many people, especially children and teenagers and people who go out for activities, such as agricultural mechanics, construction workers and construction workers. Experts can remind that it is not safe to use plastic cups for drinking water for a long time, and the use of plastic cups is not recommended.
The reasons are as follows: First, plastics are polymer chemical materials, often containing toxic chemicals such as polypropylene or PVC polyvinyl chloride. Drinking water in a plastic cup is inevitably used to fill hot or boiled water.
When using plastic cups to fill hot water, especially when filling boiling water, the toxic chemicals in the plastic can easily precipitate into the water, and drinking such water for a long time will inevitably cause harm to the human body. Second, plastic water cups are prone to bacteria and are not easy to wash. This is because plastic with a seemingly smooth surface is not smooth, and there are many small pores in the internal microstructure, and these small voids are easy to trap dirt and dirt, and cannot be cleaned off by conventional methods.
Third, most of the most advanced plastic cups on the market are made of polycarbonate, and bisphenol A is one of the main raw materials for the production of polycarbonate plastics. Bisphenol A is internationally recognized as a substance that can increase the risk of cancer, and is related to breast cancer, prostate cancer and precocious puberty, and its harm to the human body is similar to smoking.

Plastic water bottles are relatively safe, but there are some details that need to be paid attention to. First of all, plastic water cups are usually used for cold drinks, and it is not recommended to put hot water or beverages because the plastic may melt and release harmful substances. In addition, some studies have also shown that plastic cups that have been used for a long time or pay attention to the use of ** may release harmful substances similar to liver toxicity, Bisphenol A (BPA), which may cause damage to the body, so special attention needs to be paid to the model and quality of purchase and use.
In this regard, we can consider the user arguing that some more Huai is a safe and reliable cup instead of a plastic cup. For example, glass, ceramic or stainless steel cups are reliable choices. Compared with plastic water bottles, these cups have better resistance to high temperatures, so they can be used with confidence.
In addition, the texture of these cups is also more stable and has a longer service life, which can reduce the pollution to the environment.
Finally, we also need to pay attention to the manufacturer and sales channel. It is recommended to buy plastic water cups from regular manufacturers, and choose food-grade safe materials with a certain content, such as PP or PE materials, so that you can use plastic water cups with more regret and confidence. At the same time, when choosing sales channels, you should try to choose a business with a business license, a good reputation, and a high degree of product quality, so as to ensure that the plastic water cup you buy is relatively safer.
To sum up, plastic water cups are relatively safe, but it is still necessary to pay special attention to the quality of purchase and use, and pay attention to the details when using, and at the same time, it is also a feasible choice to choose other reliable cups, which need to be selected from the perspective of production and sales channels. <>

The water cup PC material is good.
PC material water cup is relatively safe, PC material itself is non-toxic, it is a bisphenol file, so that when A is converted into PC material, the transformation of the fruit is not complete, so it is possible to release bisphenol A toxic in case of high temperature. Do not hold water with high temperatures. When using plastic containers such as PC cups, it is necessary to store and disinfect food in strict accordance with the instructions, and use the correct method to store and disinfect.
Features of PC material:
Strictly speaking, the PC material water cup is not as safe as the glass water cup, and it is recommended to use the glass water cup, food grade stainless steel water cup or ceramic cup in the usual drinking process. Although the glass is chemical-free and easy to clean, it is easy for users to accidentally burn themselves because of its strong thermal conductivity, and if the water temperature is too high, it may cause the cup to burst, so try to avoid hot water.
PC material is a chemical compound, PC can be used as door and window glass, PC laminate is widely used in protective windows in banks, embassies, detention centers and public places, used in aircraft cabin covers, lighting equipment, industrial security baffles and bulletproof glass. PC bottle (container) is transparent, light weight, good anti-stagnation impulse, resistant to a certain high temperature and corrosive solution washing, as a first-class bottle.
When you buy a water cup made of PC material, you must pay attention to whether it has been tested by the national quality agency. Usually the plastic cup made of PC material can withstand temperatures of minus 30 degrees and 140 degrees, so everyone should pay attention to the temperature when using it.
Unsafe behavior is a dangerous practice in which employees violate labor discipline, operating procedures and methods in the course of professional activities. Unsafe behavior is an abnormal behavior that is exhibited by a person and is contrary to the psychological characteristics of the person. Behaviors that have caused or may cause accidents during construction operations are inevitably unsafe behaviors.
Because most cars now do not have airbags in the back, once they encounter a serious traffic accident, the lives of the people behind are easily "threatened".

Because it is easy for plastic utensils to dissolve the plasticizers in the water due to heat when filling hot water, which affects our health, so do not use plastic utensils to fill hot water.
