How to straighten out plastic?

So I cut the bottle and you know the main part of the bottle that is actually straight but it’s in a shape of a circle. So I cut it and trying to make it straight like a ruler. So I wonna know if you know how to straighten out the plastic fast. Well just what’s the fastest, best, cheapest way to straighten out the plastic?
Thanks.

I would lay it on a board, cover it with a cloth and set a warm iron on it until it flattens out by itself.
