How Long Will Ice Packs Keep Food Cold?
Ice packs can keep food cold for approximately 2-4 hours depending on the size of the ice pack, the type of food, and the temperature of the surrounding environment. It is important to use enough ice packs to keep perishable food at a safe temperature of 40°F or below to prevent bacteria growth and food spoilage. For longer periods of time, it is recommended to use a cooler with ice or dry ice.
