Japan launches domestic food cooling bags

Japan launched a household food cooling bag. The bag is a double-layer vinyl bag, about 20cm long and 16cm wide. The outer bag contains a polymer absorbent polymer coagulant. A microporous hole is provided on the inner surface of the bag. If the bag is put into the water for 15 to 30 minutes, the water will slowly infiltrate into the bag and form a gel-like coolant, which is then placed in the refrigerator for cooling. When traveling, people can take cold or cold drinks from the refrigerator and put them in cold storage bags. They can take their food freely, especially for midsummer use.
