The top 10 fastest-growing plastics suppliers in the U.S.

Posted by IndustryNet on Wednesday, July 12, 2017

100000063_QDC_Plastic_Blow_Molding_PlantPlastic has been around for some time, but it was not until the mid-1800s when the material truly emerged as a cost-effective replacement for ivory. From there, the material's use flourished in other sectors from aerospace to automotive, medicine to movies, and everyday life.

Polyethylene, the most widely used plastic today, started as World War II-era insulation. Resins, originally developed for the maritime industry, now cross multiple sectors. Acrylonitrile-butadiene-styrene plastics, or ABS, are used in appliances, helmets, and other common items.

IndustryNet tracks all U.S. plastics companies and their employees. According to IndustryNet’s analysis of the plastics industry, the United States is home to 281 plastics companies employing over 15,000 individuals, with average annual sales topping $1.3 billion. Overall industry growth has been strong, with 5 percent of the plants reporting employment increases and 3 percent reporting sales growth over the past year
