These dishwasher tablets (Finish Powerball Shine) seem to be covered in plastic!

Film-covered dishwasher tablets

But that can't possibly be true since there's no unwrapping, and they're completely soluble in water.

What is the film made of?

  • $\begingroup$ Keep in mind "plastic" encompasses many different chemical species. Many are soluble in water. $\endgroup$ Jul 31, 2015 at 17:31

    $\begingroup$ The MSDS sheets for the product you've linked to are available via email in the U.K. Here in the U.S., the manufacturer makes them available online. That said, there is not a U.S. product called Finish Powerball Shine, but here is a link for Finish Powerball Quantum Max (Fresh Scent) where it is stated that "Ingredient polyvinyl alcohol" functions as a "Dissolvable Film." You might peruse the other U.S.-hosted Finish products to find a more suitable equivalent. $\endgroup$
