What are the raw materials used in the production of plastic products?
Cling film, plastic film are such materials, heat resistance is not strong. Usually qualified PE cling film will appear hot when the temperature exceeds 110 degrees, and will leave some plastic preparations which can not be decomposed by human body. And wrapped with plastic wrap food heating, food grease is easy to preserve the harmful substances dissolved in the film. Therefore, the food into the microwave oven before, to remove the cling film wrapped.
The poisonous and harmful substances produced by plastics of this kind of material come from 2 aspects. One is the single molecule vinyl chloride which is not completely polymerized in the process of production, and the other is the harmful substance in the plasticizer (two). These 2 substances in the high temperature and fat when easy to precipitate, toxic substances enter the human body with food, easy to cause cancer. At present, the containers for this material are less used for packaged food. If the family has this kind of material, don't let it heat.
Bearing cleaning supplies, plastic containers and bath products currently used in supermarkets and shopping malls in the plastic bag is made of this material, can resist high temperature of 110 DEG C, indicating the food use of plastic bags can be used for holding food. Bearing cleaning supplies, plastic containers and bath products can be repeatedly used carefully after cleaning, but these containers are usually not good cleaning, easy residual cleaning supplies, become a breeding ground for bacteria, it is better not to use circulation cleaning is not thorough so.
Common mineral water bottles and carbonated beverage bottles are made of this kind of material which can not be recycled or hot water. Its heat-resistant temperature is only 70 degrees, only suitable for warm drinks or cold drinks, high temperature liquid or heating, easy to deformation, will dissolve the harmful substances. The scientists also found that the plastic could release carcinogens in 10 months. Therefore, when the beverage bottle is used up, it should be thrown away. It should not be used as a drinking cup or used as a storage container to hold other foods, so as not to cause health problems.
