According to this it takes about 50 tons of PE granules to make about 40 Kilometers of clingfilm.

Only the individual bar wrappings were the standard clear plastic (stronger and more rigid than cling film), the two and four pack wrappers were the folk-like wrappers that you would see on Kit-Kats and the like.
Interesting, but none of these actually answered my question.
Do the math yourself. The answer is there lol.
