Indianapolis cannot ban polystyrene foam takeout containers or coolers. Indiana Code 36-1-3-5.6 sweeps in any auxiliary container regulation, and a 2018 update extended the preemption explicitly to cover food packaging materials beyond plastic bags.
Polystyrene foam ('Styrofoam') containers, clamshells, cups, plates, and coolers are common targets of municipal bans in coastal cities. Indiana's auxiliary container preemption (IC 36-1-3-5.6) defines auxiliary containers broadly to include cups, plates, bowls, trays, and packaging made of paper, plastic, foam, or fiber, used to transport or contain food or merchandise. Indianapolis therefore cannot ban polystyrene takeout containers, charge a fee for them, or require restaurants to substitute compostable alternatives. Some Indy hospitals and IndyGo facilities have voluntarily eliminated foam, and Indianapolis Public Schools transitioned away from foam trays in 2018, but these are procurement choices, not citywide mandates.
No retailer penalties exist because Indianapolis cannot adopt a polystyrene ban; any local ordinance attempting to do so would be invalidated under the state preemption statute.
