The invention relates to a macromolecular film and discloses a comfortable, free and sporty macromolecular film capable of preventing
electromagnetic radiation. The comfortable, free and sporty macromolecular film comprises a base layer (1) and a PET (Polyethyleneglycol Terephthalate) protective layer (2) and is characterized in that an
electromagnetic radiation preventing layer (3) is arranged between the base layer (1) and the PET protective layer (2) and is a silver-
fiber layer, the base layer (1) is made from fabrics, the fabrics are formed through the mutual-sink-and-emerge interweaving of warps and wefts, either the warps or the wefts are elastic covered yarns, and each elastic covered
yarn consists of a spandex
yarn located at the center and a plurality of nylon low-stretch yarns covering the spandex
yarn. According to the comfortable, free and sporty macromolecular film capable of preventing
electromagnetic radiation, disclosed by the invention, the electromagnetic
radiation preventing layer is arranged between the base layer and the PET protective layer and is the silver-
fiber layer, an internal
magnetic field is formed by the silver-
fiber layer and an electrical appliance generating electromagnetic
radiation, and then, the electromagnetic
radiation is shielded, so that the effect of preventing the electromagnetic radiation is achieved. The macromolecular film has great comfortable, free and sporty feeling.
