What is are packing peanuts edible?

Packing peanuts are not edible. They are made of expanded polystyrene foam (EPS), which is not food-grade material and can cause health problems if ingested. The foam is treated with flame retardants and other chemicals that can be harmful if consumed. Eating packing peanuts can cause gastrointestinal blockage, choking, or other serious health issues. It is important to keep packing peanuts away from children and pets and dispose of them properly. Some companies use biodegradable packing peanuts made from cornstarch or other plant-based materials, which are safe for the environment but still not edible.
