The present invention provides a biodegradable grating sheet and an article thereof, and a manufacturing method thereof. The manufacturing method of the biodegradable grating sheet comprises the following steps: 1) drying the biodegradable polymer or modified product thereof at 50–120°C; 2) extruding into a sheet by an extruder at 120–250°C, wherein the front surface of the sheet is provided with a uniform lens array with the same surface curvature, and the sheet becomes a biodegradable grating sheet after cooling and shaping. The method for manufacturing a biodegradable article with stereoscopic images comprises the following steps: 1) making the biodegradable grating sheet into a grating sheet with stereoscopic vision images; 2) manufacturing an article with stereoscopic images. The biodegradable grating sheet and article of the present invention can be completely decomposed into water and carbon dioxide in nature without harm to the environment, overcoming the biggest drawback of preparing grating sheets from petroleum-based chemical materials at present.
