Embodiment 1
[0038] The shed film of the present invention has a three-layer composite structure, anti-fogging agent is used in the inner layer, and the thickness ratio of the three layers is 3:4:3. Each layer is made of polyethylene as a matrix and functional additives are added in proportion. The co-extrusion blow molding process is processed and formed, and the three-layer co-extrusion blow molding process is a known technology, and the parts by weight ratio of each layer of the formula is as follows:
[0039] Outer layer formula (by weight ratio):
[0040] 45.6894 parts of low-density polyethylene resin with a melt index of 0.3-0.7g / 10min
[0041] 45.6894 parts of linear low-density polyethylene resin with a melt index of 0.7-1.0g / 10min
