Abstract
A waterproof heat-preservative film is formed by providing a melt of a waterproof material, mixing phase-change microcapsules with the melt to form a mixture, solidifying the mixture and pulverizing the solidified mixture to form particles containing phase-change microcapsules, and forming a film with the particles by means of extruding or blowing.
