Ice packs do keep food cold, but their efficiency depends on several factors including external temperature, insulation of the container, and the number and size of ice packs used. For best results, use them in an insulated cooler and consider pre-chilling your cooler and items before packing. Ice packs can maintain food at a safe temperature of below 40°F for about 4-6 hours in moderate conditions. For longer periods, combine with other cooling strategies or use more substantial, high-performance ice packs.
