Lyondellbasell Industries N.v.
A maker of the plastics that fill everyday life, LyondellBasell is one of the world's largest producers of polyethylene and polypropylene — the resins behind everything from food packaging and pipes to car parts and medical gear, sold under brands like Moplen, Alathon, and Purell. The company was born in 2007 when Basell Polyolefins, a joint venture of BASF and Shell, bought Lyondell Chemical Company, which itself traced back to a 1985 spinoff of Atlantic Richfield (ARCO). Its name is simply the two merged companies' names stitched together.
