How long do cooler bags keep food cold?

You probably bring lunch to work or college every day, so all the food inside your lunch bag must stay cold. After all, who wants to take a bite of reheated yogurt or find their meal moldy inside the lunch box? It's disgusting.

With a cooling pack, insulated lunch bags stay cold for about 6-8 hours, but it's not foolproof. This is an approximation, and it all depends on several factors. I invite you to consult our explanatory article on how a cooler bag works to find out more.

However, do not leave your fresh food in the insulated lunch bag for too long. It is necessary to put them in the refrigerator as soon as possible.

Your insulated bag will stay cold for approximately 6h – 8h, depending on the conditions of use. According to a study by scientists, the danger zone for bacteria is between 4 and 60°C. At this temperature, bacteria proliferate faster, and your meal may go moldy. Your lunch bag can easily climb into this area if left unrefrigerated for too long.

If you don't have quick access to a refrigerator, you can use techniques to keep your food fresh longer.

Should I put the lunch bag in the fridge?

As the name suggests, a cooler bag has thermal insulation. Therefore, placing your bag in the refrigerator will not cool its contents. However, the coolness present inside the lunch bag will take less time to dissipate.

Therefore, your insulated lunch bag must be refrigerated, especially if you do not plan to eat your meal quickly. This will allow you to keep your food safe until lunchtime!

It's a good idea to put your lunch bag in the coolest place. A standard refrigerator sits at an average temperature of 2°C, well outside the danger zone for bacteria. So, a lunch full of meat, dairy, or any other perishable food should be put in the fridge as soon as possible.

Where to put ice in a cooler bag?

Some lunch bags or coolers have a dedicated space specifically for cooling packs. The cooling pack should go in this space, in a zippered pocket inside the bag, or at least somewhere inside the bag.

However, some state that you must place the ice on top of the food. Others will say that the bottom of the bag is better. Either way, your best bet is to make sure you have a cooling pack somewhere in your bag or cooler when traveling. And as soon as you can, be sure to put the lunch bag in the fridge!

TIP: We recommend you to buy cooling pack from Britwrap as it is the best protective packaging company all over the UK.
