       | 
       | "... sell its coating in the United States, branded as valPure
       | V70. It has been used in 22 billion cans since 2017. That's a
       | modest fraction of the estimated 350 billion aluminum beverage
       | cans and 100 billion steel food cans produced each year
       | worldwide."
       | 
       | I'd prefer to use these cans over the BPA alternative.

         | information available to consumers.

         | 
         | I have a friend who used to work in the coatings lab for PPG
         | circa 2007. He had a handful of chemicals to choose from that
         | he would blend and test until the outcome fit the manufacturing
         | requirements. It was not tested for toxicity before it was sent
         | on to manufacturers and into your soda/veggie can.

           | This article is about TMBPF, a BPF, not a BPS. It is also
           | structurally similar to BPA and the article is all about the
           | struggle to effectively determine whether it is safe (and how
           | this struggle has been very open which according to the
           | article is not common for chemical companies). Many toxicity
           | studies have been done and seem promising.

       | Avoid plastics. Any move away from BPA is merely rebranding.
