Embodiment 1~6
[0062] Embodiments 1-6 provide a PE film whose raw material composition is shown in Table 1.
[0063] Table 1 Outer layer, middle layer and inner layer raw material composition (parts by weight) of PE film
[0064]
[0065] The preparation method of the PE film of embodiment 1~6 is:
[0066] S1. Mix the raw materials of the outer layer, middle layer, and inner layer of the PE film according to the ratio, add them to the extruder respectively, and extrude and granulate to obtain outer layer pellets, middle layer pellets, and inner layer pellets;
[0067] S2. Add the outer layer pellets, middle layer pellets, and inner layer pellets to a three-layer co-extrusion blown film machine respectively, melt and extrude through a three-layer co-extrusion process, and undergo inflation traction, cooling, and corona treatment , film winding to prepare the high-performance PE film;
[0068] Among them, the conditions of corona treatment are: input voltage 220V, output voltage 6kV, vehi...
