Raw materials are non-toxic plastic products itself, but in the process of made into plastic bags and other products, in order to change the plastic's physical characteristics, will add some additives, such as adding organic acids to make plastic bags appearance look crystal clear, adding antistatic agent make good unscrewed the plastic bags, etc. However, this additive is national standard, according to the amount of impurities and kinds of impurities, which can be divided into food grade and industrial grade standard. If the finished product is added to the additive, it is strictly according to the food grade standard, generally harmless to the body; If the standard is not reached, the harmful impurities in the additives are likely to exceed the standard. Once the plastic bags are in high temperature, these impurities such as heavy metals can be easily decomposed.
