Butter packaging?

I eat a lot of butter and stopped using the butter wrapped in alu foil after i saw a video about it containing carcinogenic materials. Ubelievable that they put that stuff on butter. So now i eat butter wrapped in paper, but the paper seems to have some sort of non-stick layer. Anybody knows if this is safe? If not, would it be a good idea to cut off a thin layer of all sides of the butter and throw that away, then keep the butter in a glass container?
