摘要:
The present invention provides a transparent film and a transparent film for agricultural use, each of which has a cellulose ester film and a protective layer, and each of which is configured such that: the protective layer is arranged on at least one surface of the cellulose ester film; the protective layer has a film thickness of 5-50 μm; the protective layer has an ultraviolet transmittance of 50% or less; and the moisture permeability of the transparent film in an environment at 40°C at a relative humidity of 90% is 400 g/m2/24 h or more. Consequently, the present invention provides a transparent film and a transparent film for agricultural use, each of which has achieved a good balance between high moisture permeability and high light resistance.
