Based on population density, Indiana led the country with 15.2 plastics jobs per 1,000 nonfarm jobs, followed by Michigan at 14.5 and Wisconsin at 14.2.
California and Michigan each ranked first in two specific plastics jobs categories. California is home to 11.3 percent of plastics wholesale trade jobs and 8.3 percent of captive plastic production. Michigan has 19.9 percent of mold making jobs and 12.9 percent of plastics machinery jobs.
In other job categories, Ohio had 7.9 percent of plastic product jobs and Texas had 21.1 percent of materials and resins jobs.
Pineda cited data showing that almost 90 percent of U.S. plastics production is for personal use as proof that the industry "has social benefit."
"The industry hasn't oversupplied the market by any means," he said. "It's been very responsible in providing plastics production to efficiently meet the needs of the market."
The Federal Reserve's recent decision to lower U.S. interest rates by half a percentage point also should benefit the plastics industry in several ways, Pineda added, including by boosting construction activity.
"This [interest rate] cut was appropriate for a less robust but still expanding economic outlook," he said. "A larger cut would have indicated a contraction, while a smaller cut wouldn't have made much impact."
"There's a growing belief in a soft landing [for the U.S. economy], which should restore vibrancy to the plastics industry."
