Embodiment

[0082] The content of the present invention will be described in detail by the following examples, but the scope of the present invention should not be limited to the examples.

[0083] [Preparation of agricultural film (five-layer structure)]

[0084] Agricultural films with a five-layer structure of the outermost layer, the middle layer, and the innermost layer were prepared respectively. The preparation method is as follows: using methods such as co-extrusion T-die method, co-extrusion air-cooled inflation method, co-extrusion water-cooled inflation method, etc., respectively make the outermost layer (transparent layer), the first middle layer (white Pigment layer), the second intermediate layer (black pigment layer), the third intermediate layer (white pigment layer), and the innermost layer (transparent layer) five-layer agricultural film. The film thickness of the prepared agricultural film is about 150 μm.

Embodiment 5

[0087] Example 5 An agricultural film having a four-layer structure of the outermost layer and the middle layer (1 to 3) was prepared. Example 6 An agricultural film having a four-layer structure of an intermediate layer (1 to 3) and an innermost layer was prepared. The preparation method is as follows: using methods such as co-extrusion T-die method, co-extrusion air-cooled inflation method, co-extrusion water-cooled inflation method, etc., respectively make the outermost layer (transparent layer) or the innermost layer (transparent layer) , a four-layer agricultural film of the first intermediate layer (white pigment layer), the second intermediate layer (black pigment layer), and the third intermediate layer and the innermost layer (white pigment layer). The film thickness of the prepared agricultural film is about 150 μm.

Abstract

The present invention puts forward an agricultural film having a pigment added thereto and having an excellent choking resistance, light-blocking stability, and film strength. The agricultural film is provided with an outermost layer, one or more intermediate layers, and an innermost layer. The outermost layer is a layer on the side at which UV rays or heat rays are received, and comprises a polyolefin resin, a first light stabilizer, a second light stabilizer, and an UV absorption agent. The first light stabilizer is a triazine-based light stabilizer, and the second light stabilizer is a non-triazine-based light stabilizer. The intermediate layer comprises a polyolefin-based resin and a pigment. The innermost layer is a layer on the side at which UV rays or heat rays are not received, and comprises a polyolefin resin.

Description

[0001] Related applications [0002] This application claims Paris Convention priority on the basis of Japanese Patent Application No. 2013-118209 (filed on June 4, 2013), and the application specification, drawings, etc. of the patent application on which this Paris Convention priority is claimed are based. Included in this case manual. technical field [0003] The present invention relates to an agricultural film, in particular to an agricultural film having good chalking resistance, light-shielding stability, and film strength (shading property). Background technique [0004] (Shading) Agricultural films have been used for the following purposes in the past: shading cultivation for seedling cultivation, growth and flowering of agricultural and horticultural plants, night light cultivation, summer shading and heat insulation cultivation, and shading and insulation in livestock breeding. hot etc. [0005] Generally, white pigments such as titanium oxide and black pigments...
