How can the cooler bag extend the heat preservation time?
The main function of the insulation bag is to isolate the heat conduction inside and outside, so it can keep heat and cold. The surface of the tin foil can reflect heat and extend the cooling time. No matter what items need to be refrigerated, the shelf life is shorter at room temperature, and it can be used within the validity period if it is placed in the cooler bag.
There are two ways to extend the heat preservation time. One is that the innermost layer can be made of plastic material. The main function is to reduce odor and dirt. Even if the bento or beverage is spilled, the plastic surface is easy to clean and conductive. Inferior plastic can also lock the temperature more. Second, if you need to keep cold, you can put in the cold preservation agent directly, which can also effectively improve the cold preservation effect! Insulation and cold storage bags have many uses, and they can be switched freely between insulation and cold storage. They are a good helper for daily life and an unbeaten choice for gifting!
