If it's ones use and out plastic, I'll stick with glass and metal. I know someone is about to say they still cause CO2 and they do, but these materials can at least be easily recycled. This means when the rest of the chain becomes green (for lack of a better phrase) then so will this part.
If however it's using fully reusable and fully recyclable (not just incinerator "recycling") then sure, absolutely no issue. Fully behind it. I'm willing to bet, however, all of the money in my pocket that that's not the case here though sadly.
