Can mineral water be exposed to the sun? Many people say that because the high temperature of the sun will cause the plastic to decompose, the toxic substances inside will melt into the water. If you drink this kind of water, it will cause great harm to the body, and there is a risk of cancer. It is absolutely forbidden to drink it. So, is this really the case?
Picking up a bottle of mineral water, you will find a triangle symbol at the bottom of the bottle, there is also a number "1" inside, and the three letters "PET" are marked below the symbol. This PET represents the name of the material used to make mineral water bottles-polyethylene terephthalate.
This material is an organic polymer material, and its chemical properties are relatively stable in daily life. It is not only resistant to acid, alkali and grease, but also resistant to corrosion by most solvents. It is an internationally-used material. Food-grade plastic for liquids such as water and beverages. And its melting point is above 250 degrees Celsius, and chemical changes must be above 100 degrees Celsius. Pour hot water into the mineral water bottle, the mineral water bottle will deform, but it will not produce toxic chemicals and will not dissolve into the water.
Although plastics are okay, there are still many people who say that plasticizers added to plastics are toxic. Is it okay to be exposed to the sun? In fact, plastic bottles made of PET do not need to use plasticizers such as phthalates in the production process.
The main toxicity of plasticizers is that they contain bisphenol A. At present, most countries in the world have banned the addition of bisphenol A to food-grade plastics. In my country, there are strict regulations on the use of bisphenol A. If the plastic contains bisphenol A, the number will be marked as "7", which means that it cannot be directly made into food-grade plastic.
Therefore, mineral water will not dissolve harmful substances when exposed to the sun, so there is no need to worry.
