Example Embodiment
[0057] Example 1 (control)
[0058] Manufacturing of 65μm thick light-scattering agricultural film.
[0059] The formula and performance of agricultural film are as follows:
[0060]
[0061] The manufacturing method of the agricultural film is:
[0062] Table 1
[0063]
[0064] According to the ratio shown in Table 1, it is divided into three layers: inner, middle and outer. The components are stirred in a blender and mixed evenly. The film is made into a cylindrical film through a three-layer co-extrusion film blowing unit. After being compacted into a flat film, the scattering type agricultural film is produced after the upper and lower traction rollers and the winder. The speed, current and melt pressure and temperature of each layer of the extruder are shown in Table 2 below. The temperature of the outer barrel is 210°C, the temperature of the middle barrel is 190°C, and the temperature of the inner barrel is 189°C.

Example Embodiment
[0067] Example 2 (this application)
[0068] Manufacturing of 68μm-thick light-scattering agricultural film.
[0069] The formula and performance of agricultural film are as follows:
[0070]
[0071]
[0072] The manufacturing method of the agricultural film is:
[0073] table 3
[0074]
[0075] According to the ratio shown in Table 3, it is divided into three layers: inner, middle and outer layers. The components are stirred in a blender and mixed evenly. The three-layer co-extrusion film blowing unit is used to form a cylindrical film, which is passed through the upper traction roller. It is clamped into a flat film, and the scattering type agricultural film is produced after the upper and lower traction rollers and the winder. The speed, current and melt pressure and temperature of each layer of the extruder are shown in Table 4 below. The temperature of the outer barrel is 205°C, the temperature of the middle barrel is 185°C, and the temperature of the inner barrel is 190°C.
