The present invention relates to a preparation method for a bacterial cellulose thin film, in which the transmittance of a visible light to the bacterial cellulose thin film at a wavelength of 550 nm is about 90%. The preparing method provided by the present invention comprises preparing a sealed and flexible bag which is filled with a culture solution inoculated with bacteria, and laying the flexible bag horizontally to cultivate the bacteria for a period of time until a bacterial cellulose thin film is formed. The thin film provided by the present invention can be used as skin dressings, packaging materials or industrial materials.本發明係關於一種細菌纖維素薄膜之製備方法,該細菌纖維素薄膜對550nm波長的光具有約90%的穿透度,本發明的製備方法包含於一密封的、內部充滿已接種細菌的培養液的可撓曲袋內,在水平靜置該可撓曲袋情況下進行細菌培養一段時間直到形成一片細菌纖維素薄膜。本發明所製得之薄膜可做為皮膚敷料、包裝材料或工業材料等應用。
