[0009] (2) The woven steel mesh is fed into a PE film laminating machine and overlapped with a layer of PE film, with the steel mesh on top and the PE film on the bottom. The PE film laminating machine then sprays glue on the upper surface of the steel mesh and the upper surface of the PE film from above the steel mesh. Finally, another layer of PE film is pressed on the upper surface of the steel mesh by the PE film laminating machine. The PE film is glued together with the PE film on the lower surface of the steel mesh by the sprayed glue, and the finished product is made.

[0010] Furthermore, the stainless steel wire used is made of 304 stainless steel, and the wire diameter of the steel wire is 0.21 mm.

[0013] The beneficial effects of the present invention are as follows: the steel wire mesh of the PE composite film with high tear resistance of the present invention provides certain support for the PE film and greatly enhances its tear resistance. At the same time, the PE film can block and alleviate the corrosion of the steel wire mesh by external substances, and plays a good protective role on the steel wire mesh. Therefore, the PE film and the steel wire mesh cooperate with each other, greatly extending the service life of the composite film product.
