Practical: How to identify toxic plastic wrap

Thread Content

PVC (polyvinyl chloride) plastic wrap contains carcinogenic substances and is harmful to the human body, whereas plastic wrap made of PE (polyethylene) is safe. Most plastic wrap available on the market is made from three materials: PVC, PE, and PVDC (polyvinyl chloride). 　　PE and PVDC are safer choices. Most experts believe that PVC food wrap poses significant risks to human health. The harmful substances contained in this type of wrap can easily leach out; once they enter the body through food, they can cause cancer. In particular, they interfere with the body’s endocrine system, leading to breast cancer in women, congenital defects in newborns, reproductive problems in men, and even mental illnesses. The United States, Japan, South Korea, and others have **already completely banned it**. Many consumers, although they find the plastic wrap covering the prepared foods in supermarkets to be clean, have doubts – wondering whether it might be unhealthy 　　In fact, to determine whether an insurance film is toxic, consumers can use the following methods: First, PVC plastic wrap has greater transparency, stretchability, and stickiness compared to PE plastic wrap ； II. When PVC plastic wrap is burned, the flame turns black, black smoke is produced, and there is a pungent odor; it does not drip oil, and it extinguishes itself once removed from the heat source. In contrast, when PE plastic wrap burns, the flame is yellow, it is odorless, it drips oil, and it can continue to burn even after being taken away from the heat source.
