What are the materials for plastic bottles?
Most of the beverage bottles are made of plastic. They are mainly made of polyethylene or polypropylene and added a variety of organic solvents. Polyethylene, polypropylene, these two materials non-toxic, tasteless, used to fill drinks, etc., is very safe for the human body. But once the polyethylene is subjected to high temperature or acid corrosion, it dissolves slowly and releases organic solvents, which can cause harm to the human body.
There are many ways of making polyethylene, the most common of which is the polymerization of ethylene at temperatures of 200~300 C and 1000~2000 atm. In polyethylene, no other substance is doped. This low density polyethylene obtained, soft texture, for sunlight, air, water and chemical reagents, have high stability, so no external stabilizer, plasticizer, stabilizer and plasticizer are mostly toxic or highly toxic.
It has been reported that eating foods contaminated with polyethylene molecules for a long time can cause dizziness, headaches, nausea, loss of appetite, memory loss, and even anemia. Therefore, the use of plastic bottles vinegar, human health has no harm. Therefore, the family should use glass ware instead of plastic products, such as condiment products. The use of plastic products should pay special attention to, do not touch vinegar, detergents, etc., to avoid direct sunlight, high temperature, etc., so as not to occur chemical reactions. In addition, when you buy plastic tableware, you should choose goods with PE (polyethylene) or PP (polypropylene) mark, decorative patterns less, colorless, tasteless, smooth surface of plastic products.
