    Acting like every plastic is the same makes as much sense as acting like every metal is the same…

    But it seems it has more to do with the sealing process used.

    Caps are painted/coated, then crimped around the outside of the bottle. It sounds like the crimper never gets cleaned, and since it’s not sealed till crimped, we get some of those tiny particles shot into the bottle from the force of it.

    So to bring it all back, the plastic bottles are manufactured with plastic that is “food safe”. The coating on the caps is not. So very little leaches from a bottle, everything from the cap dust is just going to float around in there.

      Most plastic caps are made from a colored resin. I used to buy them from the manufacturers. We coated the Tito’s caps with the copper color. The silver ones are metallized in a similar way.
