The present disclosure discloses a low-water-vapor-permeability polyolefin-elastomer film and its preparation method. The film comprises: 50-100 mass parts of a matrix resin, 0-40 mass parts of a modified resin, 0.001-2 mass parts of an activator, 0.1-3 mass parts of an organic peroxide, 0.02-5 mass parts of an assistant cross-linker, 0.02-2 mass parts of a silane coupling agent, 0.005-2 mass parts of a light stabilizer, and 0-20 mass parts of a water blocking filler. In the present disclosure, by adding the modified resin and the activator that have an active group, a cross-linking degree and a cross-linking density of the film are improved, and a water-vapor permeability is reduced; by adding the water blocking filler, the water blocking property of the film is further improved, thereby ensuring reliability of the assembly, and prolonging service life of the assembly.
