PROBLEM TO BE SOLVED: To provide a non-porous high moisture permeable film having high moisture permeability [3,000-6,000 g/(m<2> .24 h) or more] and excellent not only in mechanical strength but also in transparency and flexibility. SOLUTION: The high moisture permeable film is constituted by laminating a moisture permeable non-porous polyurethane film and a porous polyurethane film. |
