[0009] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0010] like Figure 1 As shown, the vacuum coating equipment for improving the barrier performance of high-barrier materials includes an unwinding section 1 and a rewinding section 2, a coating roller 3 is provided between the unwinding section 1 and the rewinding section 2, a coating source 4 and an ion source 5 are provided on the coating roller 3, and a passing roller 6 is provided between the unwinding section 1 and the coating roller 3 and between the rewinding section 2 and the coating roller 3. High-energy ions bombarding the surface of the material can make the material molecules more densely arranged, thereby improving the barrier performance of the material.

[0011] Preferably, the unwinding section 1 is provided with a base film 7 , and a passing roller 6 and a coating roller 3 are provided for the base film 7 to pass through.

[0012] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0013] Although the unwinding unit 1, the winding unit 2, the coating roller 3, the coating source 4, the ion source 5, the roller 6, the base film 7 and other terms are often used in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
