Paper or plastic” will no longer be a choice at grocery store checkout lines in California under a new law signed by Gov. Gavin Newsom.

California Governor Gavin Newsom signed dozens of bills into law on Sept. 22 including one piece of legislation that bans all plastic shopping bags offered by grocery stores. The law takes the previous ban of thin plastic bags a step further by forbidding the use of thicker plastic bags that were described as reusable or recyclable.
