Foam carry-out containers and lids hold food for serving, taking meals on the go, or storing leftovers. Foam insulates food better than paper, plastic, or fiber containers. These carryout containers are more durable than paper or foil containers. They do not biodegrade and are not recyclable. Some states restrict the sale of foam (also known as expanded polystyrene) products; alternatives to foam include, compostable, recycled, bio-based, paper, and plastic disposable equivalents.
