The present invention concerns a cooling device and method of forming and regenerating same for use in keeping perishable products cool. The cooling device includes a porous substrate that has been soaked in a first composition including at least one anti-freeze agent before being soaked in a second composition including at least one crosslinking agent and be exposed to UV irradiation. The cooling device further includes a substrate cover for sealingly covering the porous substrate after being soaked in the second composition and exposed to the UV irradiation. Prior to use, the cooling device is cooled to a desired temperature and exposed to further UV irradiation.
