Anti-static polyethylene film, preparation method and anti-static bag

The invention provides an anti-static polyethylene film, a preparation method and an anti-static bag. The anti-static polyethylene film comprises an outer-layer film, a middle-layer film and an inner-layer film, the inner-layer film is prepared from the following raw materials in percentage by mass: 15 to 25 percent of macromolecular antistatic agent and 75 to 85 percent of low-density polyethylene; the mass ratio of the high-density polyethylene to the low-density polyethylene to the medium-density polyethylene in the middle-layer film is 15: 9: 8-1: 1: 1; the outer layer film is prepared from the following raw materials in percentage by mass: 15 to 25 percent of macromolecular antistatic agent and 75 to 85 percent of polyethylene mixture; the mass ratio of high-density polyethylene to low-density polyethylene to medium-density polyethylene in the polyethylene mixture is 15: 9: 8-1: 1: 1. The anti-static polyethylene film provided by the invention has relatively good anti-static performance and relatively hi
