State had already banned thin plastic shopping bags, but new measure bans all plastic bags starting in 2026

“Paper or plastic” will no longer be a choice at grocery store checkout lines in California under a new law signed on Sunday by the governor, Gavin Newsom, that bans all plastic shopping bags.

California had already banned thin plastic shopping bags at supermarkets and other stores, but shoppers could purchase bags made with a thicker plastic that purportedly made them reusable and recyclable.
