Here at Plastics News we keep a database of plastics-related companies. Over the years we've added names from news releases and market reports. In all, 5,842 companies have been tracked in our database. 2,506 have been ranked over the years.
For 535 of them, we have recorded name changes or acquisitions. One company has 26 entries on that list. Sigma Plastics Group and Berry Global Inc. are the two highest ... but you could have guessed that from reading our published articles alone.
