One of the Best Ways to Keep Food Cold Long

Depending on the contents of your cooler, you may need to pack it differently to ensure that everything stays cold for the duration of your trip. Here are a few tips to help you pack your cooler bag so that everything stays cold. Pack items that you will need first, such as food and drinks, towards the top of the cooler. This way, you won't have to dig through everything to find what you need. If possible, pre-freeze items such as ice cream or frozen fruit. This will help keep other items in the cooler cold for longer.

The Right Size for the Right Amount of Time to Keep Things Cold

You already know that such factors as the type of insulation, the thickness of the wall as well as the size of the bag are very important. In general, though, a good rule of thumb is that the thicker the walls and the better the insulation, the longer your things will stay cold. So, if you want your cooler bag to keep things cold for a long time, make sure to choose one with thick walls and good insulation and most important the large one.
