Problems solved by technology

However, it is difficult to apply a paint containing spherical particles with a particle diameter of 1 to 20 μm while uniformly dispersing the particles therein
Moreover, the light incident on the highly light-scattering film is widely reflected, and the total light transmittance is reduced.
In addition, light scattering agents are currently expensive

Embodiment Construction

[0032] Embodiments of the present invention are described below with reference to the accompanying drawings. In the following description based on the drawings, the same or similar regions are marked with the same or similar reference numerals. However, the drawings are schematic diagrams, and it should be noted that the relationship between each thickness and the size of each plane, the ratio of the thickness of each layer, and the like are different from actual ones. Therefore, specific thicknesses and sizes can be determined from the description below. Also, it is a matter of course that the drawings include multiple spatial relationships and parts with different respective ratios.

[0033] Furthermore, the embodiments described below exemplify apparatuses and methods embodying the technical subject matter of the present invention. The technical subject matter of the invention can be varied in various ways within the scope of the claims.

[0034] The present invention is...

Abstract

The invention provides a transparent based-membrane and transparent resin layer. At least one of based-membrane and resin layer contains UV absorbers, and the transmissivity of ultraviolet which wavelength is 380nm is set at 60% or less. The surface of resin layer is provides a great amount of irregular objects, the total transmissivity is 85% or more and the diffusion transmissivity is 6% or more.

Description

technical field [0001] The present invention relates to a light-scattering composite agricultural film for effectively cultivating crops, in particular to a light-scattering composite agricultural film formed by compounding a transparent resin layer with a large number of irregularities on the surface on a transparent base film. Background technique [0002] So far, polyethylene films, polyvinyl chloride films and polyester films have been used as coating materials for agricultural access and piping areas. Moreover, UV-resistant films formed by mixing UV absorbers with such films, as well as films that enhance wettability, are already commercially available. In recent years, it has been known that in the case of using a light-scattering film as the above-mentioned film, the scattered light uniformly reaches the entire plant, which enhances the rate of photosynthesis thereof, and therefore, the use of the light-scattering film is effective for the cultivation of plants of. ...
