A layer of non-woven fabric is added to the surface of the non-woven biological ice bag to prevent water mist from appearing on the surface of the ice bag, which can effectively absorb the water mist appearing on the surface of the deicing bag to a certain extent. The method is to directly place it in a cold storage or refrigerator and let it freeze before use, without the need for further steps such as water injection and absorption, making it more efficient and simple. Suitable for cold and fresh transportation of aquatic products, sea insects, seafood, meat, dairy products, beverages, vaccines, reagents, household products, flowers, solder paste, etc. Generally, it is used together with foam boxes or special cold chain boxes to achieve the effect of refrigerated transportation.
