@publius Old way: multi-sheet paper and glue. New way: polyethylene single sheet, tensioned with surrounding springs or steel cable. Less mess, less ladder danger!
@publius there is some saving to the plastic ones because they can be taken down and re-used or moved between sites, which is impossible with the paper. And the plastic can theoretically (but probably not realistically) be recycled whereas the paper cannot. Plastic also lasts much longer, paper has to be replaced often
