Something that is not on the ingredients? A lot of them have lactose (I think) as a filler. I don't see how plastic would bind. I'd think plastic would just come out the other end anyhow. Ask him how he knows this.
I know some spices use SILICON DIOXIDE as a free flowing agent . My first impression upon reading this ingrediant was that the are putting plastic in my spices(Silicon made me think of implants hense the plastic connection). I have since found out that it is merely a form of sand. That's my best guess as to what you are refering to.<br><br><br><br><a href="http://en.wikipedia.org/wiki/Silicon_dioxide" target="_blank">http://en.wikipedia.org/wiki/Silicon_dioxide</a>
