Nothing seems to kill ice quicker than the hot rays of the sun. This is regardless of how efficient the cooler or its insulation is. This is because sunlight tends to bypass all these workarounds and finally end up bringing the inner temperature up of the cooler.  

Thus, it is best to keep the cooler at a place where there is a shade or where there is no direct sunlight. Even receiving the sunlight indirectly can bring up the temperature inside although it is likely to be a slower process than the one with direct sunlight.

2. Go for the Best Insulation

Another major factor in keeping your ice stay longer is the insulation of the cooler. This is perhaps one of the most lucrative tips working for most of us in most cases. 

The simplest way to do so is to use sacks to cover the external area of the cooler. This simply means adding an additional layer of insulation so that the outside heat does not enter inside.

Another way of boosting insulation is to place a single layer of foil made up of aluminum and then put ice on the same. The science here is that the foil reflects both light and heat far from the cooler whenever you open it.  You can even use the foil for covering the external surface of the cooler.

3. Utilize Dry Ice

This is perhaps an ideal way to keep ice from melting too soon. Unlike the normal ice, dry ice transforms from solid to gas. In other words, the property of dry ice will prevent your food from becoming soggy. Furthermore, dry ice is cooler too due to which quick melting perhaps is no longer an issue.

However, handling dry ice with hands can end up burning them. Thus, it is safe to handle it with gloves. In addition, dry ice releases carbon dioxide gradually, which means using it in a cooler kept in a vehicle is generally unsafe. To ensure safety, keep the windows of the vehicle open.

4. Add Salt

Just put some sea salt in the water that you are going to freeze for making ice. Doing so simply brings down the freezing temperature. This means that the ice will be colder than the frozen water.
