Plastic bottle: it's not as terrible as you think.
recently, some people have said that plastic products are harmful to health, and even drinking directly with your mouth against the mouth of the plastic bottle may cause chronic poisoning, so you don't use plastic bottles anymore. In urban and rural areas of China, a considerable number of families are reluctant to throw away plastic products such as Coca cola bottles and mineral water bottles, and use them to contain oil, salt, sauce (A and D are synonymous with the front), vinegar, wine, tea, soybeans, mung beans and other miscellaneous grains. When they hear that using plastic bottles will be poisoned, they dump all the contents, and some even pour drinks into cups
in this regard, relevant experts from the China Plastics Processing Industry Association pointed out that plastic packaging is basically high molecular compounds, with stable chemical structure. It is not as terrible as some people think, and can be reused many times

Plastic products such as Coke bottles and mineral water bottles will deform after being filled with boiled water, but it will not affect their safe use, but the appearance will change greatly, and their internal molecular structure will not change in essence, nor will they produce toxic and harmful substances. When using a metal brush to clean the plastic bottle, even if grinding the outside or inside of the plastic bottle really solves the long-standing problems of 3D printing customers, it only destroys the surface finish, rather than the molecular structure. As for the storage of highly corrosive acid-base solutions, plastic materials are the safest packaging materials, but consumers need to be reminded that the name of toxic and harmful solutions must be marked on the bottle and placed out of the reach of children
from the birth of plastic to today, plastic products have gone through a century of history with mankind, and have made indelible contributions to social and economic progress and the improvement of people's living standards. As for some prejudices and misunderstandings people have about plastics today, it is more due to the negative impact on society caused by some illegal manufacturers who use recycled materials or inferior raw materials to replace safe and hygienic raw materials to produce food packaging. Today, with the development of science and technology, our engineers and technicians are fully capable of ensuring the safety of plastic food packaging to human health. As long as it is a qualified product produced by regular manufacturers in accordance with technical standards, consumers can use it with confidence
