Cooler Bags

What are cooler bags and why should you have one?

Cooler bags and cooler boxes are an indispensable accessory for anyone who needs to transport food and drinks while keeping them at a low temperature. They work on the principle of thermal insulation – a special inner layer (often made of PEVA or aluminium foil) prevents heat from the surroundings from getting inside. As a result, they keep the contents cool for much longer than an ordinary bag. Whether you are looking for a lightweight cooler bag for a day out or a larger cooler box for the car, you will find it here.

The main reason to get a cooler bag or box is food protection. Especially during the summer months, there is a risk of cold cuts, cheeses, yoghurts or fresh fruit spoiling quickly. A cooler bag effectively prevents bacteria from multiplying and keeps food and drink fresh. They are ideal for picnics, days spent at the beach and longer car journeys on holiday, as well as for everyday shopping for frozen or chilled food. Instead of single-use packaging, cooler bags and boxes are a more eco-friendly and, in the long run, more economical solution. For optimal performance, we recommend using ice packs.

How to choose the right cooler bag?

Choosing the right cooler bag or cooler box depends on your specific needs. Before you decide, think about how often and for how many people you will be carrying food, and how long you need to keep it cool.

Size and capacity

Capacity is a key parameter. For an individual taking a snack to work, small bags and boxes of up to 5 l will suffice. If you are planning shorter trips with your family or a small group of friends, look for bags and insulated baskets of around 20 l. For large family picnics or holidays, cooler boxes with a capacity of 25 l and more are ideal. When choosing, consider not only the volume of food but also the space that the ice packs will take up.

Type of insulation and cooling performance

The performance of cooler bags varies. Foam insulation (PE) tends to be more effective than aluminium foil alone. The thickness of the insulation also matters. To significantly extend the cooling time, it is a good idea to use an ice pack. Without one, the bag works only as a passive insulator; with one, it becomes an active source of cold.

How to use ice packs correctly?

1. Freezing: Freeze the ice packs thoroughly before use (ideally overnight).
2. Placement: Place the ice packs on top of the food – cold air naturally sinks downwards.
3. Quantity: The more ice packs (or the larger the ice pack), the longer the bag will stay cool.
