Thermoboxes and thermobags – how useful in the heat?

One of the main conditions for a good rest in the summer heat is isothermal products. It is designed for long-term storage of food and maintaining the temperature: on the beach you will have a cool lemonade, and in the autumn park – hot homemade mulled wine.

For a family trip, pick up a roomy bag or a picnic set, and for a short walk, a lunch box is useful. For isothermal products to work properly, buy cold storage for it. We will tell you how to choose them.

We choose the right batteries

Isothermal products will maintain the required temperature due to the heat-reflecting inner layer. To increase the time during which the products will remain chilled twice, you need to choose the right number of batteries, starting from the volume of the bag.

How many cold accumulators do you need?

The optimal number of batteries is calculated as follows: 1 liter of bag volume * 60 g of battery. Several small or medium containers will evenly distribute the cold throughout the bag and help preserve food more efficiently.

Let's give examples for our products. So, for bags up to 10 liters, you will need 2 batteries of 400 g each (IcePack 400). More capacious options – with a volume of 17 liters or 20 liters – will require 2-3 pieces, for 25 liters – 4 pieces, for 29 liters – 4-5 pieces

Please note: The examples shown assume the purchase of 400g batteries. The range also includes IcePack 750, they will need less due to the larger volume of the battery itself.

How to use cold accumulators: memo

Cold accumulators are reusable, but they are “charged” in different ways. When it comes to refrigeration, containers should be kept in the freezer for at least 6 hours before use, and 12 hours for complete freezing. After that, they are taken out and immediately placed between the walls of isothermal products.

In order to maintain heat, the battery must be heated. You can do this in one of two ways:

Place the battery in boiling water (+85 °C) for 5-7 minutes, then carefully remove it with tongs or a slotted spoon, wipe dry and place in a bag or lunch box.
Place the battery in a container of water and microwave for 4 minutes at 280W. After that, carefully remove with a slotted spoon, wipe and place in isothermal products.

Important!

In both cases, the water should completely cover the battery.

Forget about the weekend on the couch in front of the TV – go on a picnic, plan new trips and exciting walks, and isothermal products will take care of the freshness of snacks and drinks!
