Existing law in California requires that rigid plastic containers and rigid plastic bottles be marked with a resin identification code. Bill AB 906, signed by the governor on October 15, creates a definition for PET; beginning on October 1, 2018, containers and bottles marked as “1-PET” will have to meet the new definition. In practice, the new definition will mean that PET-G plastics will no longer be able to be marked as “1-PET” and will have to be marked as “7-Other”.
