Manufacturing companies across North America announced closures and layoffs impacting more than 480 workers in June 2026, contributing to a year-to-date total of over 2,800 affected employees in the packaging sector. Major industry players, including International Paper, Smurfit Westrock, and Ineos Styrolution, cited economic viability and margin pressures as primary drivers for the recent site shutdowns.
Why are packaging manufacturers closing sites?
Companies are narrowing their operational footprints to combat shifting market demand and rising overhead costs. Ineos Styrolution stated that its Channahon, Illinois, polystyrene facility is “no longer economically viable,” leading to a planned closure in the fourth quarter. The site currently employs approximately 100 people and produces 400,000 metric tons of material annually.
International Paper is also consolidating its network. The company announced four specific shutdowns for the third quarter, impacting 330 workers. These closures include a sheet plant in Aurora, Illinois; converting plants in Elk Grove, California, and Barrington, New Jersey; and the cessation of preprint operations at a facility in Richwood, Kentucky.
What is the impact of recent industry consolidation?
The pace of industry contraction remains steady, with Packaging Dive tracking over 2,800 layoffs and closures in North America so far this year. Smurfit Westrock is the latest to signal a reduction, announcing the closure of a folding carton facility in Lebanon, Tennessee, effective Aug. 14. According to a notice filed with the state, the 52 affected employees at the Lebanon site do not have bumping rights.
Beyond planned layoffs, the industry faces ongoing supply chain uncertainty. Production at Nippon Dynawave’s Longview, Washington, site remains suspended following a fatal implosion on May 26. This incident has forced customers to seek alternative suppliers in an already tightening fiber-based packaging market.
How do these trends compare to previous years?
The current wave of closures reflects a broader trend of “right-sizing” among major packaging firms. While International Paper’s 330-employee reduction is significant, it is part of a larger, multi-facility strategy to optimize fiber production. This contrasts with the sudden, site-specific disruptions like the Nippon Dynawave incident, which create immediate, unplanned supply gaps rather than strategic market exits.
Did you know?
A “bumping right” is a provision in some labor contracts that allows a more senior employee to take the job of a less senior employee during a layoff. At the Smurfit Westrock Lebanon facility, workers do not have these rights, meaning their positions are eliminated entirely without the possibility of internal transfer based on seniority.
