Title:
AGRICULTURAL FILM
Document Type and Number:
WIPO Patent Application WO/2018/131429
Kind Code:
A1
Abstract:
Provided is an agricultural film that allows sunlight to pass therethrough, with the film itself generating heat due to photothermal conversion, thereby enabling the temperature inside of an agricultural house to be raised. This invention contains black inorganic particles including a metal element, and a light-transmissive resin 100. The content of the black inorganic particles including a metal element is 0.05 to 0.20 parts by weight with respect to 100 parts by weight of a light-transmissive resin. A volume frequency histogram of the black inorganic particles including a metal element has a particle size distribution in which the maximum volume frequency of components of 5 μm or more is 2.0% or less, such volume being measured by the laser diffraction scattering method.
