This category is for *directories* of plastics manufacturers (including rubber), and is not a listing of individual plastics manufacturing firm websites. Individual plastics firm sites will only be considered if they have a list of many other plastics manufacturers on the site.

Websites containing sizeable lists of plastics manufacturers with information about the companies and, importantly, that make clear which companies (if not all) are actual plastics manufacturers, will be considered. Directories of plastic wholesalers, distributors, and suppliers without companies that manufacture will not be considered in this category, and e-Portals and eMarketplaces will also not be considered (unless they also have a directory listing of manufacturers on the site).
