Example Embodiment
[0060] Example 1
[0061] The ultra-high performance plastic film in this embodiment has a single-layer structure, and a single-layer extrusion casting process is selected during preparation, and the thickness of the prepared film is 0.097 mm.
[0062] The formula weight composition of the film is as follows: 9.52% ultra low density polyethylene, 85.72% metallocene linear low density polyethylene, 3.33% color masterbatch, 1.43% other additives.
[0063] The performance of the plastic film prepared by the above formula is compared with the performance of the existing operating table cloth on the market as follows:
[0064]
[0065] It can be seen that the tensile strength of the film in this example is more than 2 times that of the existing operating table cloths on the market; the dart impact is more than 5 times that of the existing operating table cloths on the market; the tear strength is higher than that of the existing operating table cloths on the market. There are 1.1 times mor...

[0069] Example 2
[0070] The ultra-high-performance plastic film in this example has a two-layer structure of A layer and B layer. The two-layer extrusion casting process is selected during preparation. The thickness of the prepared film is 0.097mm. The A layer and B layer structures are both formulated as follows :
[0071] The weight composition of the A-layer formula is as follows: 9.52% ultra-low density polyethylene, 85.72% metallocene linear low density polyethylene, 3.33% color masterbatch, 1.43% other additives.
[0072] The weight composition of the B layer formula is as follows: 9.76% ultra-low density polyethylene, 87.8% metallocene linear low density polyethylene, 0.98% color masterbatch, and 1.46% other additives.
[0073] The performance of the film prepared by the above formula is compared with the performance of the existing operating table cloth on the market as follows:
[0074]
[0075] It can be seen that the tensile strength of the film in this example is more tha...

[0079] Example 3
[0080] The ultra-high-performance plastic film in this embodiment has a three-layer structure of A-layer, B-layer and C-layer. A three-layer extrusion casting process is selected during preparation. The thickness of the prepared film is 0.097mm, of which A-layer, B-layer and C-layer The layer structure uses the following formula:
[0081] The weight composition of the A-layer formula is as follows: 22.83% ultra-low density polyethylene, 68.49% metallocene linear low density polyethylene, 7.31% color masterbatch, 1.37% other additives.
[0082] The weight composition of the B-layer formula is as follows: 14.63% ultra low density polyethylene, 68.29% metallocene linear low density polyethylene, 14.63% high density polyethylene, 0.99% color masterbatch, 1.46% other additives.
[0083] The weight composition of the C layer formula is as follows: 9.52% ultra-low density polyethylene, 85.72% metallocene linear low density polyethylene, 3.33% color masterbatch, 1.43% addit...
