The thermal bag is designed for storing and transporting various products (for example, food and drinks) while maintaining the temperature regime for a certain period of time.
As a rule, the inner surface of the thermal bag is usually covered with a special material that provides thermal insulation.
On the outside, it can have a soft or hard shell to protect the products from external influences.
Such products are widely used both in everyday life and on trips and picnics to preserve or transport food and drinks at the required temperature.
But instead of spending money on such an undoubtedly necessary purchase, we suggest you make an analogue of a thermal bag with your own hands.
And for this you will need nothing more than the familiar “bubble wrap” film, which is usually used to protect fragile things.
All you need to do is place the bubble wrap in a regular bag.
Try to have as many layers as possible – the ability of the structure to maintain the required temperature depends on this.
