Stable plastic sheeting?

I have had a collection of makeshift greenhouses over the past few years, built partly using old double glazing panels and for the roof I have used new and jolly expensive corolux panels which seem to be holding up ok. But as they are only part made with glass I have used plastic sheeting to fill in the gaps bought online from a scaffolding company.

Quite frankly the plastic is utter rubbish after a year despite being sold as 'UV stable' it is breaking up horrible chemicals all over the plots. I would like to do away with the old ramshackle greenhouses and invest in a modern polytunnel but am wary of doing so as it seems that the cheapy type everyone else bought last year at my allotment site has caused angst amongst the plotholders as the plastic on those has not even lasted a season leaving the plotholders out of pocket by 90 quid each.

I have also been speaking to a friend who is a chemist and he has heard that plastics are being made from cheaper materials these days so just will not last as long as they should.

There are polytunnels over the site which have been there for at least ten years and have moss growing on them they are so old and not a rip or flaky mess in sight.

Are there ANY suppliers of polytunnel covers who can supply a genuine UV stable cover? I am loathe to shell out over £300 for something that will only last a couple of years, and as a word of warning do not buy scaffold cover as it is just for scaffolding, unless you can get it free of course.
