Some families are reluctant to discard disposable coke bottles and water bottles and use them to hold oil, salt, sauce, vinegar, wine, tea and food. However, recently some people have heard that plastics are detrimental to health, and even drinking directly from the mouth to the plastic bottle mouth may cause chronic poisoning, so simply pour the drink into a cup for drinking. Some people also dumped white wine, vinegar, and disinfectant etc. In fact, these practices are caused by the misunderstanding of macromolecule compounds, such as Coke bottles and mineral water bottles, which will be deformed after being boiled in boiling water, but will not affect their safe use, but will only undergo a major change in their appearance. The structure has not changed in nature, and it will not produce toxic or harmful substances. When using a metal brush to wash these two bottles, even if the outer surface or inner surface of the bottle is worn, it only destroys the surface finish without causing damage to the molecular structure. As for the caustic acid and alkali solution containing strong corrosion, plastic materials are the safest packaging materials. What needs to be reminded is that the names of poisonous and harmful solutions must be marked on the bottle and placed in a place that children cannot reach.
Background material: According to experts, Coke bottles are generally made of polyester materials, which are colorless and have good transparency. After being filled with carbonated beverages, they are pressure-resistant, abbreviated as PET. Mineral water bottles generally use polyvinyl chloride materials, light blue, and their transparency is higher than that of polyester. Material is slightly poor, referred to as PVC; medium-to-high grade baby bottles generally use polycarbonate, resistant to cooking, not afraid of high temperatures, and can withstand microwave heating. The above three types of macromolecular compounds are widely used in the packaging industry, and their emergence has driven the revolution of the packaging industry and conforms to the food packaging standards of the National Bureau of Standards. Moreover, there is no authoritative professional literature that shows its carcinogenic, damage to the health of the fetus and infants, pregnant women resulting in miscarriage and so on.
