In daily life, plastic bags can be said to be one of the daily necessities that people can't lack. People can use plastic bags to hold various items. They can be used for snacks and vegetables, but many people use plastic. I don’t know how to choose when I am in the bag, because there are some differences in the raw materials used by the manufacturer when making the bag, and some inferior bags are not only toxic during use, but also harmful to the human body. In the process of packaging the bag, you should understand the correct selection method.
If you use plastic bags to hold food, you should use food-specific bags. If you choose a bag that does not meet the standard of use, it will affect the safety of food. The easiest way to distinguish this is to smell the bag. If the smell of the bags is very pungent, it proves that these bags are added with a large amount of chemical reagents during the production process, and such bags cannot be used to directly hold food.
