Insulated bags can help to keep food frozen for a short period of time, but they are not designed for long-term freezing. Insulated bags are designed to keep items cold, but they do not have the same level of insulation as a dedicated freezer. If you need to keep food frozen for an extended period of time, it is best to use a dedicated freezer or a portable cooler with a powerful freezing unit. These types of coolers are specifically designed to maintain low temperatures for long periods of time, and they will be able to keep your food frozen much more effectively than an insulated bag.
