752 views

The number of ice packs needed to keep food cold depends on several factors such as the type of food, the cooler's insulation, and the ambient temperature. As a general rule, use one medium-sized ice pack per every 2-3 hours you need to keep things cold in a standard lunch box, and 2-3 large ice packs for a 24-hour period in a larger cooler. For best results, place ice packs on top of the items, as cold air travels downwards.
