“Genpak realigned our manufacturing facilities to coincide with legislative changes and consumer demand,” said Jeff Hebert, President of Genpak. “Although we must pivot a sector of our operations, we are deeply grateful for the dedicated employees at our Cedar City manufacturing facility. They have been an essential part of our success, having served the community for over 30 years.”

Regarding the impacted employees, Hebert added, “Genpak is committed to aiding affected employees by providing severance packages, outplacement support, and benefits assistance.”

The legislative bans reflect the move towards more [sustainable](https://www.plasticsiq.com/topics/sustainability/) [packaging](https://www.plasticsiq.com/topics/packaging/) solutions. With nearby states including California, Colorado, Oregon, and Washington, opting for such bans has led to the plant's closure.
