Packaging Dive reported the development on 2026-03-18. The Flexible Packaging Association and the American Forest & Paper Association are among the plaintiffs seeking a preliminary injunction to block enforcement of SB 343 come October.
The report places the news in a wider commercial context. A coalition of business groups filed a lawsuit in the U.S. District Court for the Southern District of California on Tuesday challenging SB 343, California’s 2021 “truth in labeling” law that’s set to take effect this October. The coalition alleges that SB 343 will not increase recycling, and will instead increase consumer confusion — a key issue that drove the legislation’s development years ago.
For the food sector, the practical implications extend beyond the immediate announcement. The lawsuit comes just over six months out from an Oct. 4, 2026, go-live date for SB 343.
Attention now turns to how companies, customers and regulators respond. Plaintiffs also include the California Restaurant Association, California Grocers Association, Pet Food Institute, Snac International and the Print Creative Alliance, among others. The complaint alleges that SB 343 violates the free speech clause of the First Amendment to the U.S. Constitution, and that businesses face undue burdens.
