im not exactly sure to tell you the truth... because i know alot of stuff they use in the medical industry are the worst plastics. I know they use vynil in alot of areas of a hospital because it is strong and doesnt degrade where other plastics will.
but i am talking more about like things used in surgury, like i said I am not 100% sure on the topic. I know alot of plastics are extracted from things like corn and such. But there are natural plastics like latex, which even though they are naturaly sourced... many people are also very allergic to it.
