The present invention relates to the field of film materials, in particular to a modified polymer film and a preparation method therefor, and a metallized polymer film and the use thereof. By carrying out corona treatment on the surface of a polymer layer such as polyethylene, polypropylene, polyethylene terephthalate and the like, a polar modifier can be uniformly coated on the surface of the polymer layer to form a modified layer tightly combined with the polymer layer, so that a surface of a low-polarity polymer layer is endowed with a lasting high polarity and correspondingly high surface tension, and thus can stably and tightly combine with a metal layer and other high-polarity high-surface-tension material layers for a long time, effectively expanding usage scenarios of a non-polar polymer substrate layer. The preparation method features a simple and feasible treatment process, low cost, high treatment efficiency and easy expansion. The surface tension of a prepared modified polymer film can be 68 mN/m, and will not obviously reduce after the film is stored for three months.
