(Polyethylene) is a very safe chemical material, used for bone bonding There is absolutely no problem with food preservation in bags. In contrast, polyvinyl chloride is a polymer of a chemical substance called vinyl chloride. Vinyl chloride itself is harmful to the human body. Although its polymer polyvinyl chloride is harmless in principle, any chemical substance The polymerization is not complete, so a certain amount of vinyl chloride is not completely polymerized but cannot be separated from it. This unpolymerized vinyl chloride is the culprit of carcinogenic materials.
Both are hard plastic. In addition to being used as plastic wrap and bone bags, they also have many similar uses. Safety and long service life are the strengths of bone bag materials. From the analysis of the extraction methods of these two materials, the production cost of PTFE should be lower, because it is extracted directly from petroleum, and there is an additional processing step in the production.
