Foam containers are lightweight packaging products made from expanded polystyrene (EPS) or similar materials. They are commonly used for food storage and takeout, providing insulation to keep hot foods warm and cold foods chilled. Their design often includes lids, making them convenient for transporting meals. These containers are popular in restaurants and catering services due to their affordability and durability. However, they are not biodegradable, raising environmental concerns. Many places are now exploring alternatives, such as biodegradable containers or reusable containers, to reduce waste and promote sustainability.
