"These pellets get heated, mixed with colours and then injection moulded or, I suspect, rolled into sheets of some description."

IIRC from an episode of How It's Made or a similar program, they use air to blow a huge balloon-like structure 3 or 4 stories high of clear plastic in a continuous manufacturing process (so I suppose it must be a cylinder rather than a balloon) Quite impressive from what I remember, but no, not rolled into sheets to make money.
