The invention belongs to the technical field of high polymer materials, and particularly relates to a biodegradable material as well as a preparation method and application thereof. The biodegradable material comprises the following components: poly (butylene adipate/terephthalate) (PBAT), polylactic acid (PLA) and a filler, the filler comprises metal powder, and the metal powder has a spherical, sphere-like or cubic structure. The biodegradable material provided by the invention bends and deforms along with the action of external force like a metal wire, does not rebound after losing the action of the external force, and has excellent shape retention capability, and the all-plastic nose bridge made of the biodegradable material also has good metal texture, and can be used for manufacturing the nose bridge. The all-plastic nose bridge strip is suitable for manufacturing disposable masks in an injection molding or extrusion mode. And meanwhile, the biodegradable material disclosed by the invention also has goo
